Installing the A6828A Adapter  
Overview of Installation Steps  
Overview of Installation Steps  
Here is a high-level view of the steps for installing the A6828A HBA:  
Step 1. Review the recommendations for performance (see “Performance  
Tuning” on page 11).  
Step 2. Ensure that you have all the materials you will need (see “Preparing for  
Installation” on page 12).  
Step 3. Determine what you need to do (if anything) to configure auto  
termination for the A6828A adapter (see “Auto Termination” on page 37).  
Change the jumper position (see “Using the Jumper for Controlling Auto  
If you do not need to change the position of the jumper, go to step 4.  
Step 5. Attach any external SCSI devices you want to connect to the adapter (see  
SCSI ID (see “SCSI IDs” on page 25).  
Maximum data transfer rate (see “Maximum Data Transfer Rate” on  
page 27).  
Auto termination (see “Auto Termination” on page 37).  
Bus width (see “Bus Width” on page 39).  
Before setting the SCSI ID, Maximum data transfer rate, and Bus width  
HP-UX system supports setting of these parameters in the BCH menus  
(see Table 2-2 on page 22).  
Step 7. Install the c8xxSCSI driver from the latest HP-UX bundle or HP IT  
Resource Center (ITRC) at http://itrc.hp.com.  
See “Installing the SCSI Driver” on page 50.

Installing the A6828A Adapter  
Performance Tuning  
Performance Tuning  
To get the best performance from the A6828A adapter, HP recommends  
the following things:  
Increase the number specified for the scsi_max_qdepthkernel  
tunable parameter:  
— HP-UX 11.0: scsi_max_qdepthis a static tunable that you can  
change in SAM (“Kernel Configuration” screen “Configurable  
Parameters” screen). Note that because this is a static tunable,  
you will need to reboot the system after changing its value.  
— HP-UX 11i: scsi_max_qdepthis a dynamic tunable; therefore,  
no system reboot is needed to change the parameter’s value. See  
“SCSI Queue Depth Management” in the HP-UX 11i Release  
Notes for more information about this tunable.  
If you see “queue full” messages in the /var/adm/syslog.logfile,  
you can avoid those messages by reducing the value for  
scsi_max_qdepth.  
Install the A6828A adapter in a PCI4X or PCI2X slot in the HP-UX  
system.  
Do not put any Single Ended (SE) SCSI devices on the same SCSI  
bus as Low Voltage Differential (LVD) SCSI devices. Doing this  
changes the entire bus to SE, which limits the bus to Ultra SCSI (40  
MB/s).  
consider giving those devices the higher priorities on the bus (SCSI  
ID 7 is usually assigned to the HBA). See “SCSI IDs” on page 25 for  
more information.  
Ensure to set the adapter’s maximum data transfer rate to the  
correct rate (see “Maximum Data Transfer Rate” on page 27 for more  
information).  
Ensure to have the correct SCSI hardware configuration. Domain  
Validation can detect some configuration problems (see “Domain  
Validation” on page 98).

Installing the A6828A Adapter  
Preparing for Installation  
Preparing for Installation  
Installation of the A6828A adapter requires disassembly of some system  
components. Before beginning the installation, see the HP-UX system’s  
manual for detailed instructions about installing host bus adapters in  
the PCI slots.  
To install the HBA, you need the following:  
One HP A6828A SCSI HBA  
One grounding (ESD) kit (shipped with A6828A)  
Any other tools needed for installing components in the HP-UX  
system (for example, screwdrivers); see the system’s documentation.  
NOTE  
The maximum number of SCSI HBAs you can install in any HP-UX  
system is equal to the maximum number of corresponding card slots in  
the system. For example, if a system has four PCI card slots, you can  
install four SCSI PCI HBAs in that system, assuming that all the PCI  
card slots are empty.  
Check the latest SCSI support matrix for systems that support the  
A6828A adapter. The support matrix is available at http://docs.hp.com  
under the Networking and Communications section.

This section contains information on installing the A6828A HBA in an  
HP-UX system (including Online Addition and Replacement [OLAR]).  
WARNING  
CAUTION  
The installation procedures in this section require opening the  
computer cabinet, which might expose you to high-energy  
(high-amperage) circuits and sharp edges in the equipment  
chassis. Ensure to remove all rings, watches, and other jewelry  
before opening the cabinet.  
The A6828A adapter contains electronic components that can easily be  
damaged by small amount of static electricity. To avoid damage, follow  
these guidelines:  
Store the adapter in its antistatic plastic bag until you are ready to  
install it.  
Work in a static-free area, if possible.  
Handle the adapter by the edges only. Do not touch electronic  
components or electrical traces.  
If you must lay the adapter down, place it on a non-conductive mat or  
surface.  
Use the ESD kit that is provided with the adapter. Follow the  
instructions included with the kit.  
Use a suitable ground—any exposed metal surface on the system  
chassis.  
Before beginning the installation, and without removing the adapter  
from its antistatic bag, inspect the adapter for any signs of obvious  
damage, such as chipped or loose components. Contact Hewlett-Packard  
if the adapter is damaged.  
Install the A6828A HBA in your HP-UX system according to the  
documentation for the system.

Installing the A6828A Adapter  
NOTE  
As stated earlier, although the A6828A HBA is supported on only 64-bit  
HP-UX 11.0 and 11i, you can install the adapter in either a 32-bit or  
slot, to get maximum performance. However, you can install the adapter  
in a PCI2X, PCI1X, or shared PCI slot, if necessary.  
When you have finished installing the A6828A HBA, go to section  
“Connecting External SCSI Peripherals” on page 19.  
Online Addition and Replacement—HP-UX 11i Only  
Online Addition and Replacement (OLAR) is the ability of a PCI  
host bus adapter to be replaced in or added to an HP-UX system  
designed to support this feature, without the need for completely  
shutting down and then rebooting the system or adversely affecting  
other system components. The system hardware uses the per-slot power  
control combined with OS support to enable this feature.  
Check the latest SCSI support matrix that contains information on the  
HP-UX systems that support OLAR of the A6828A adapter. The support  
matrix is available at http://docs.hp.com under the Networking and  
Communications section.  
IMPORTANT  
Certain “classes” of hardware are not intended for access by users. At  
this time, this includes superdome systems. HP recommends that these  
systems be opened by a qualified HP engineer only. Failure to observe  
this requirement can invalidate any support agreement or warranty to  
which the owner might otherwise be entitled.  
You can add or replace an OLAR-compatible adapter in either of the  
following ways:  
Using the SAM utility.  
Issuing command-line commands, through rad, that refer to the  
c8xxOLAR script (/usr/sbin/olard.d/c8xx).  
14  
Chapter 2  
 
     
Installing the A6828A Adapter  
Installing the A6828A Adapter  
HP recommends that you use SAM instead of the radcommand to  
perform OLAR procedures. This is because for the most part, SAM  
prevents you from performing OLAR procedures that would adversely  
affect other areas of the system. This is not true when you use the rad  
command.  
For detailed information on using either of these two procedures, see  
Configuring HP-UX For Peripherals. You can order that document from  
Hewlett-Packard, or you can view, download, and print it from  
Table 2-1 below explains some important OLAR-related terms.  
Table 2-1  
Important OLAR Terms  
Term  
Meaning  
OLAR  
All aspects of the OLAR feature,  
including Online Addition (OLA)  
and Online Replacement (OLR).  
Power Domain  
A grouping of one or more  
interface adapter slots that are  
powered on or off as a unit.  
(Note: Currently, multi-slot  
power domains are not  
supported.)  
target adapter / target adapter  
slot  
The interface adapter that will be  
added or replaced using OLAR,  
and the adapter slot it is in.  
affected adapter / affected  
adapter slot  
Interface adapters and the  
adapter slots they are in, and  
which are in the same power  
domain as the target slot.  
IMPORTANT  
In many cases, other interface adapters and slots within the system are  
dependent on the target adapter. For example, if the target adapter is a  
multiple-channel adapter, suspending or deleting drivers for the target  
adapter slot also suspends individual drivers for the multiple hardware  
paths on that adapter.  
Chapter 2

Installing the A6828A Adapter  
Installing the A6828A Adapter  
During an adapter replacement operation, SAM performs a Critical  
Resource Analysis (CRA), which checks all channels on the target  
adapter for critical resources that will be temporarily unavailable while  
the adapter is shut down.  
Planning and Preparation  
As mentioned earlier, for the most part, SAM prevents you from  
performing OLAR procedures that would adversly affect other areas of  
the HP-UX system. See Configuring HP-UX For Peripherals for detailed  
information.  
Critical Resources  
Replacing an adapter that is still operating can have adverse  
consequences. As power to the slot must be off when the old adapter is  
removed and the new adapter is inserted, you must consider the effects  
of shutting down the adapter’s functions.  
This is particularly important if no online failover or backup adapter to  
pick up those functions is installed. For example:  
Which mass storage devices will be temporarily disconnected when  
the adapter is shut down?  
Will a critical networking connection be lost?  
A critical resource is one that would cause a system crash or prevent the  
operation from completing successfully if the resources were temporarily  
suspended or disconnected. For example, if the SCSI adapter to be  
replaced connects to the unmirrored root disk or swap space, the system  
will crash when the adapter is shut down.  
During an OLAR procedure, it is essential to check the targeted adapter  
for critical resources, as well as the effects of existing disk mirrors and  
other situations where an adapter’s functions can be taken over by  
another adapter that will not be affected.  
As mentioned earlier, SAM performs a thorough CRA automatically, and  
presents options based on its findings. If you determine that critical  
resources will be affected by the procedure, you can replace the adapter  
when the system is offline. On the other hand, if you are required to take  
an action immediately, you can use the radcommand to try an online  
addition of a backup adapter and deletion of the target adapter.

Installing the A6828A Adapter  
Adapter Compatibility  
This section explains adapter compatibility considerations for  
performing OLA and OLR.  
Online Addition (OLA) You can add multiple adapters at the same  
time. While adding an adapter online, the first issue you must resolve is  
whether the new adapter is compatible with the system. Each  
OLAR-capable PCI slot provides a set amount of power. The replacement  
adapter cannot require more than the available power.  
The adapter must also operate at the slot’s bus frequency. A PCI adapter  
must run at any frequency lower than its maximum capability, but an  
adapter that could operate at only 33 MHz would not work on a bus  
running at 66 MHz. The SCSI A6828A HBA operates at 66MHz. The rad  
command provides information on the bus frequency and power available  
at a slot, as well as other slot-related data.  
If your system has one or more slots that support OLAR, and you want to  
use OLA to install the A6828A in one of those slots, install the adapter in  
your HP-UX system according to the procedure described in the  
“Managing PCI Cards with OLAR” chapter of the Configuring HP-UX  
Peripherals manual.  
After you add a new A6828A adapter, SAM tries to locate the SCSI c8xx  
driver. If SAM is unable to locate the driver, you cannot use the new  
adapter until you install the driver (remember that driver installation  
requires a system reboot). If SAM locates the driver, it determines  
whether the new adapter is functional. If the adapter is not functional,  
SAM displays an error message.  
Online Replacement (OLR) While replacing an interface adapter  
online, the replacement adapter must be identical to the adapter being  
replaced, or at least be able to operate using the same driver as the  
replaced adapter. This is referred to as like-for-like replacement and  
should be adhered to, because using a similar but not identical adapter  
can cause unpredictable results.  
For example, a newer version of the target adapter that is identical to the  
older adapter in terms of hardware might contain an updated firmware  
version that could potentially conflict with the current driver. In  
addition, the old adapter and new adapter must have the same PCI  
identifiers (subsystem ID and device ID).

Installing the A6828A Adapter  
The PCI specification allows a single physical adapter to contain more  
than one channel. A single channel SCSI adapter cannot be replaced by a  
dual channel adapter, even if the additional channel(s) on the adapter  
are identical to the original SCSI adapter.  
When the replacement adapter is added to the system, the appropriate  
driver for that adapter must be configured in the kernel before beginning  
the replacement operation. SAM ensures the correct driver is present.  
(In most cases, the replacement adapter will be of the same type as an  
adapter already in the system, and this requirement will be  
automatically met.) Keep the following things in mind:  
If the necessary driver is not present and the driver is a dynamically  
loadable kernel module (DLKM), you can load it manually. See the  
section “Dynamically Loadable Kernel Modules” in Configuring  
HP-UX For Peripherals for more information.  
If the driver is static and not configured in the kernel, then the  
adapter cannot be added online. The adapter could be physically  
inserted online, but no driver will claim it. Note that the SCSI c8xx  
driver is a static driver.  
If you have any question about the driver’s presence, or if you are not  
certain that the replacement adapter is identical to the existing adapter,  
you can use the ioscancommand together with the radcommand to  
investigate.  
SAM does not allow the A6828A HBA to be suspended in either of the  
following situations:  
If the adapter is being used (for example, if a file system is mounted).  
If the CRA shows that a critical resource (for example, swap space or  
the root file system) depends on the adapter.  
After you replace an A6828A adapter online, SAM checks the  
replacement adapter to make sure it is permitted, according to the  
like-for-like rules. If the adapter is permitted, SAM automatically  
activates it. If it is not permitted, SAM displays an error message.

Connecting External SCSI Peripherals  
Connecting External SCSI Peripherals  
The A6828A adapter is capable of communicating with Low Voltage  
Differential (LVD) or Single Ended (SE) SCSI devices. LVD allows up to  
12m cable lengths with multiple SCSI devices, or 25m point-to-point  
connections.  
IMPORTANT  
As stated earlier in this chapter, do not mix LVD SCSI devices with SE  
SCSI devices on the bus. If you do so, the entire SCSI bus will change to  
SE. This will limit the bus performance to Ultra SCSI (40 MB/s).  
Make all external SCSI bus connections to the A6828A adapter with  
shielded, 68-pin LVD cables. The connectors on the cable are always  
keyed to ensure proper mating.  
NOTE  
No cables or external terminators are shipped with the A6828A adapter.  
Cables are usually shipped with the external SCSI devices, and you can  
get external terminators for the A6828A HBA by ordering SCSI LVD/SE  
terminator (HP product number C2370A).

To connect external SCSI devices to the A6828A adapter, perform the  
following steps:  
Step 1. Plug the 68-pin VHDCI connector on one end of a shielded external high  
density SCSI cable into the adapter’s external connector (J2).  
Step 2. Plug the 68-pin HD connector on the other end of the cable into the SCSI  
connector on the external SCSI device.  
Step 3. If you need to connect more than one external SCSI device to the adapter,  
daisy chain them together with shielded external SCSI cables.

number C2370A). For more information on auto termination, see “Auto  
Termination” on page 37.  
When you have finished connecting the external devices, go to the next  
section, “Specifying SCSI Parameters”.

Chapter 2  
 
   
Installing the A6828A Adapter  
Specifying SCSI Parameters  
Specifying SCSI Parameters  
To ensure proper operation of the A6828A adapter, the following SCSI  
parameters that apply to the entire adapter must be configured correctly:  
Maximum data transfer rate (SCSI rate)—see “Maximum Data  
Transfer Rate” on page 27.  
Auto termination state—see “Auto Termination” on page 37.  
Bus width—see “Bus Width” on page 39.  
NOTE  
For some of these parameters, you can set the value through commands  
in the Boot Console Handler (BCH) menus (on some HP-UX systems);  
see Table 2-2 on page 22.  
The BCH menus are displayed after the system has booted and before  
the OS is running.  
If the adapter is new, the SCSI driver uses a default setting suggested by  
the system’s firmware, unless you specify a setting through the BCH  
menus (if possible). This also happens if the slot in which you install the  
adapter has no prior setting for a particular SCSI parameter  
If the adapter is new and the slot does have a prior setting, the driver  
uses that setting unless you change it through the BCH menus (if  
possible).  
If the adapter has been used in another slot or in a different system, you  
must set the SCSI parameters for the adapter back to their default  
values. This is because previously set values for the adapter cannot be  
migrated to the new slot or system. See “Setting SCSI Parameters to  
Default Values” on page 49 for the steps to follow.  
Table 2-2 is a summary of the supported HP-UX systems and the SCSI  
parameters you can set on each one. This table assumes that you have  
correct version of PDC on the HP-UX system. To know about the correct

Chapter 2  
 
Installing the A6828A Adapter  
Specifying SCSI Parameters  
SCSI IDs  
You must assign a separate SCSI ID (0 through 15 for a 16-bit SCSI bus)  
to the SCSI host bus adapter (HBA) and each SCSI device. The priority  
of the device on the SCSI bus is determined by the SCSI ID of the device.  
The order of SCSI ID priorities (from highest to lowest) is 7, 6, 5, 4, 3, 2,  
1, 0, 15, 14, 13, 12, 11, 10, 9, and 8. A device with SCSI ID 7 has the  
highest priority, and one with SCSI ID 8 has the lowest.  
When you are assigning SCSI IDs, HP recommends you to give the SCSI  
HBA higher priority than the other SCSI devices on the bus. SCSI ID 7 is  
the preset SCSI ID for the A6828A SCSI HBA, thereby giving it the  
highest priority on the SCSI bus. Set each of the other SCSI devices on  
the bus to one of the remaining SCSI IDs.  
In a multi-initiator (High Availability [HA]) configuration, multiple SCSI  
HBAs are connected to the same SCSI bus. For such configuration, the  
SCSI HBA that carries most of the traffic must be assigned a SCSI ID of  
7 (highest priority). Later, you must change the SCSI ID of each of the  
remaining SCSI HBAs on the bus from the preset setting (7) to the next  
highest priority remaining SCSI IDs (for example, 6, 5, 4, and so on).  
If you plan to boot your system from a hard disk drive on the SCSI bus,  
you must assign that drive the next highest priority unassigned SCSI ID.  
If there is only one SCSI HBA (SCSI ID = 7), the hard disk drive will be  
assigned a SCSI ID of 6. If there are multiple SCSI HBAs, the hard disk  
drive will be assigned the next highest priority SCSI ID available after  
all of the SCSI HBAs have been assigned higher priority SCSI IDs.  
Setting SCSI IDs  
To set the SCSI ID of the A6828A HBA, see “Setting and Confirming  
SCSI Parameters” on page 88.  
The peripheral device SCSI IDs are usually set with jumpers or a switch  
on the peripheral. Refer to the peripheral manufacturer’s instructions to  
determine the ID of each device and how to change it.  
IMPORTANT  
You must not have duplicate SCSI IDs on a SCSI bus; the system may  
hang or crash if you have duplicate SCSI IDs on the bus.  
Chapter 2

Make necessary changes, if any, to the SCSI IDs and record the SCSI IDs  
for future reference. To keep a record of the SCSI IDs, you can use

Installing the A6828A Adapter  
Specifying SCSI Parameters  
Maximum Data Transfer Rate  
The firmware suggested default for the A6828A adapter’s maximum data  
transfer rate is the adapter’s maximum speed (160 MB/s). The A6828A  
can communicate with all LVD or SE devices that have speeds up to 160  
MB/s. This includes the following speeds (synchronous communication  
over a Wide bus):  
Fast (20 MB/s)  
Ultra (40 MB/s)  
Ultra2 (80 MB/s)  
Ultra160 (160 MB/s)  
The actual transfer rate between the adapter and a SCSI device depends  
on the transfer rate that was negotiated between the adapter and the  
SCSI device. However, the actual rate will never be greater than the  
maximum data transfer rate set for the adapter.  
For example, if you set the A6828A’s maximum data transfer rate to  
NOLIMIT(which is same as 160 MB/s, in this case), and then connect a  
disk drive that has a maximum data transfer rate of Ultra2 (80 MB/s),  
the actual transfer rate will be 80 MB/s.  
TIP  
HP recommends that you always set the A6828A’s maximum data  
transfer rate to MAXor NOLIMIT(whichever is applicable to the system),  
adapter and a specific SCSI device. Using MAXor NOLIMITallows the  
adapter’s maximum transfer rate (160 MB/s) to be used.  
You can set the A6828A’s maximum data transfer rate in two ways, as  
shown in Table 2-2 on page 22.  
To set the maximum data transfer rate for A6828A HBA installed in  
A6828A Host Bus Adapter Installed in PA-RISC Based System” on  
page 28.  
To set the maximum data transfer rate for A6828A HBA installed in  
Itanium-based system, see “Setting Maximum Data Transfer Rate for  
A6828A Host Bus Adapter Installed in Itanium‚-Based System” on  
page 32.

Installing the A6828A Adapter  
Specifying SCSI Parameters  
Setting Maximum Data Transfer Rate for A6828A Host Bus  
Adapter Installed in PA-RISC Based System  
If the HP A6828A HBA is installed in a supported PA-RISC based  
system, use the BCH menu to set the maximum data transfer rate.  
The steps for setting the maximum data transfer rate through the BCH  
menus (if you do not want to use the default suggested by the system’s  
firmware) are mentioned later in this section.  
NOTE  
The following steps and examples are specific to an hp server rp7410.  
Menus, command syntax, and responses might be slightly different on  
other systems (for example, a maximum data transfer rate of Ultra2 is  
not allowed on some HP-UX systems).  
For command syntax and valid maximum data transfer rate values, HP  
recommends you to use the online help for the scsicommand (type  
help scsiwhen you are in the BCH “Service Menu”).  
To display and optionally change the A6828A adapter’s maximum data  
transfer rate in the BCH menus, perform the following steps:  
Step 1. At the “Information Menu,” type fv(to display the PDC version). The  
output is as follows:  
FIRMWARE INFORMATION  
Firmware Version:  
15.3  
To know about the correct PDC version information, see the latest SCSI  
support matrix available at http://docs.hp.com under the Networking and  
Communications section.  
If you do not have a correct PDC version on your system, contact your HP  
support representative.  
Step 2. Determine the HBA’s path by performing the following steps:  
a. If you are already at the “Main Menu,” type in(for “Information  
Menu”), and then go to step b.  
If you are not at the “Main Menu,” type main(to return to the “Main  
Menu”), type in(for “Information Menu”), and then go to step b.

In this example, the HBA’s path is 0/0/10/0/0(shown in bold in the  
listing above, for highlighting purposes). Note that the last (farthest  
right) digit is the channel number—0for channel A.  
Step 3. Display (and optionally change) the HBA’s maximum data transfer rate  
by performing the following steps:  
a. If you are already at the “Main Menu,” type ser(for “Service Menu”);  
go to step b.  
If you are not at the “Main Menu,” type main(to return to the “Main  
Menu”), type ser(for “Service Menu”), and then go to step b.  
b. In the “Service Menu,” type the following command:  
scsi path rate  
where pathis the HBA’s path (from step 1).  
Therefore, using the information for the HBA in the example in step  
1, type the following:  
scsi 0/0/10/0/0 rate  
This displays the HBA’s maximum data transfer rate. The output is  
as follows:  
Path (dec)  
Initiator ID SCSI Rate Auto Term Bus Width  
----------------- ------------ --------- --------- ---------  
0/0/10/0/0

In this example, the HBA’s maximum data transfer rate is MAX  
(shown in bold in the previous listing, for highlighting purposes). As  
mentioned earlier, this is the firmware suggested default setting, and  
it allows the A6828A’s maximum data rate (160 MB/s) to be used.  
30  
Chapter 2  
 
   
Installing the A6828A Adapter  
Specifying SCSI Parameters  
If you want to retain the maximum data transfer rate, type mainto go  
back to the “Main Menu”.  
If you want to change the data transfer rate (for example, to  
troubleshoot communications between the adapter and an  
Ultra-capable SCSI disk), go to step c.  
c. If you are still in the “Service Menu,” type the following command:  
scsi path rate new_data_rate  
where, pathis the HBA’s path and new_data_rateis what you want  
to change the HBA’s maximum data transfer rate to (ULTRA, for this  
example).  
Therefore, using the information for the HBA in step b, type the  
following:  
scsi 0/0/10/0/0 rate ultra  
This changes the HBA’s maximum data transfer rate to ULTRA(40  
MB/s).  
To ensure that the data transfer rate has changed, you can repeat  
step b to display the HBA’s transfer rate.  
When your troubleshooting is complete, and you want to change the  
adapter’s transfer rate back to MAX, go to step d.  
d. If you are still in “Service Menu”, type the following command:  
scsi path rate new_data_rate  
where, pathis the HBA’s path and new_data_rateis what you want  
to change the HBA’s maximum data transfer rate to (MAX, for this  
example).  
Therefore, using the information for the HBA in step c, type the  
following:  
scsi 0/0/10/0/0 rate nolimit  
This changes the HBA’s maximum data transfer rate back to MAX(160  
MB/s).  
To ensure that the data transfer rate has changed, you can repeat  
step b to display the HBA’s transfer rate.  
When you are satisfied that the maximum data transfer rate is set  
correctly, type mainto go back to the “Main Menu.”

Step 2. Find the driver handle designation <drvr_handle>.  
For the A6828A HBA, the <drvr_ handle>designation will be in the DRV  
column that corresponds to the LSI Logic Ultra160 SCSI Driver  
listing in the DRIVER NAMEcolumn.  
In the preceding example, there are two versions of the LSI Logic  
Ultra160 SCSI Driver. The <drvr_handle>designations that  
correspond to the two LSI Logic Ultra SCSI Driversare 20and 21.  
Step 3. Find the controller handle designation, <cntrl_handle>.  
At the EFI Shell prompt, issue the drvcfg command as illustrated in  
the following example:

From the output of the drvcfg command, look for the line(s) where the  
NNin Drv[NN]is same as the <drvr_handle>for the driver(s) you are  
using.  
The 2nd column, Ctrl [NN], contains the corresponding <cntrl_handle>,  
where NNis the controller handle. For example, controller handle 1A, 1B,  
1D, 1E, and 23correspond to driver handle 20, and controller handle 22  
corresponds to driver handle 21.  
Step 4. Once the driver handle and the controller handle are identified, the SCSI  
parameters can be displayed and set for any driver and corresponding  
controller (HBA) on the SCSI bus.  
Enter the drvcfg -s <drvr_handle> <cntrl_handle> command at  
EFI shell prompt. The Global Properties screen containing a list of the  
controller (HBA) to which the controller handle corresponds is displayed;  
refer to the following example:

NOTE  
If you set a particular maximum data transfer rate to the SCSI controller  
(in this example, 53C1010-66), then the same maximum data transfer  
rate is set to all the devices.  
This happens because all the devices are connected to the same SCSI  
bus, which is controlled by the SCSI controller.

Auto Termination  
When you configure the A6828A adapter’s auto termination parameter,  
you specify the adapter’s role in the SCSI bus termination, because the  
adapter might be a point of termination.  
For more information on SCSI bus termination, including a tutorial, you  
can visit HP IT Resource Center (ITRC) at http://itrc.hp.com.  
Controlling Auto Termination  
You can control auto termination in the A6828A adapter (see “Using the  
Jumper for Controlling Auto Termination” on page 38) depending upon  
the HP-UX system in which the adapter is installed (see Table 2-2 on  
page 22).  
Summary of Auto Termination Configurations  
Table 2-4 summarizes the possible A6828A auto termination  
configurations.

An external terminator might be required on the adapter, depending  
on the SCSI bus configuration. If you need an external terminator for  
the A6828A, use SCSI LVD/SE terminator (HP product number  
C2370A).  
Using the Jumper for Controlling Auto Termination  
The A6828A adapter has one set of pins that control enabling and  
disabling of the auto termination feature. The pins—labeled A_TERM  
—are at the end of the HBA that is opposite to the bulkhead connectors.  
Figure 1-1 on page 20 shows where the pin set is located on the adapter.  
The default setting of the pin set on the A6828A HBA is the open  
position (the jumper is on only one pin of its pin set). This is the auto  
termination enabled state. In this state, the A6828A automatically  
senses whether a cable from a powered SCSI device is attached and  
provides the proper termination (depending on whether a powered device  
is present).  
To disable auto termination on the adapter, change the jumper from the  
default open position to the shorted position (the jumper is on both pins  
of the pin set). This is the auto termination disabled state.  
The following Figure 2-2 shows the two jumper positions.

Bus Width  
The firmware suggested default for the A6828A adapter’s bus width is  
MAX(use the adapter’s maximum bus width [16 bits]). However, either of  
these rates can be used for the A6828A:  
8 bits (Narrow)  
16 bits (Wide)  
TIP  
HP recommends you to always use the A6828A’s maximum bus width  
(16 bits), unless you have Narrow (8-bit) devices on the bus and you are  
experiencing problems with the connection.  
You can set the A6828A’s bus width in one or two ways, depending on the  
HP-UX system the adapter is installed in (refer to Table 2-2 on page 22).

Setting Bus Width for A6828A Host Bus Adapter Installed in  
PA-RISC Based System  
If the HP A6828A HBA is installed in a supported PA-RISC based  
system, use the BCH menu to set the bus width.  
The steps for setting the bus width through the BCH menus (if you do  
not want to use the default suggested by the system’s firmware) are  
given below.  
NOTE  
The following steps and examples are specific to HP server rp7410.  
Menus, command syntax, and responses might be slightly different on  
other systems.  
For command syntax and valid bus width values, HP recommends you  
to use the online help for the scsicommand (type help scsiwhen you  
are in the BCH “Service Menu”).  
To display and optionally change the A6828A adapter’s bus width in the  
BCH menus, perform the following steps:  
Step 1. Check the PDC (system firmware) version by performing the following  
steps:  
a. If you are already at the “Main Menu,” type in(for “Information  
Menu”); go to step b.  
If you are not at the “Main Menu,” type main(to return to the “Main  
Menu”), type in(for “Information Menu”), and then go to step b.  
b. At the “Information Menu,” type fv(to display the PDC version). The  
output is as follows:  
FIRMWARE INFORMATION  
Firmware Version:  
15.3  
To know about the correct PDC version information, see the latest  
SCSI support matrix available at http://docs.hp.com under the  
Networking and Communications section.  
If you do not have a correct PDC version on your system, contact your  
HP support representative.

Installing the A6828A Adapter  
Specifying SCSI Parameters  
Step 2. Determine the HBA’s path by doing the following:  
a. If you are already at the “Main Menu,” type in(for “Information  
Menu”); go to step b.  
If you are not at the “Main Menu,” type main(to return to the “Main  
Menu”), type in(for “Information Menu”), and then go to step b.  
b. At the “Information Menu,” type io(to display I/O interface  
information). The output is as follows:

In this example, the HBA’s path is 0/0/10/0/0(shown in bold in the  
listing above, for highlighting purposes). Note that the last (farthest  
right) digit is the channel number—0for channel A.  
Step 3. Display (and optionally change) the HBA’s bus width by performing the  
following steps:  
a. If you are already at the “Main Menu,” type ser(for “Service Menu”);  
go to step b.  
If you are not at the “Main Menu,” type main(to return to the “Main  
Menu”), type ser(for “Service Menu”), and then go to step b.  
b. In the “Service Menu,” type the following command:  
scsi path width  
where, pathis the HBA’s path (from step 1).  
Therefore, using the information for the HBA in the example in step  
1, type the following:  
scsi 0/0/10/0/0 width  
This displays the HBA’s bus width. The output is as follows:

MAX  
In this example, the HBA’s bus width is MAX(shown in bold in the  
previous listing). As mentioned earlier, this is the firmware suggested  
default setting.  
If you want to retain the bus width, type mainto go back to the “Main  
Menu”.  
If you want to change the bus width (for example, because you have  
Narrow devices on the SCSI bus and you are having problems with  
the connection), go to step c.  
c. If you are still in the “Service Menu,” type the following command:  
scsi path width new_bus_width  
where, pathis the HBA’s path and new_bus_widthis what you want  
to set the HBA’s bus width to (8, for this example).  
Therefore, using the information for the HBA in step b, type the  
following:  
scsi 6/0/4/0/0 width 8  
This changes the HBA’s bus width to 8.  
To ensure that the bus width has changed, you can repeat step b to  
display the HBA’s bus width.  
When you have fixed the problem with the connection, and you want  
to change the adapter’s bus width back to MAX, go to step d.  
d. If you are still in “Service Menu”, type the following command:  
scsi path width new_bus_width  
where, pathis the HBA’s path and new_bus_widthis what you want  
to change the HBA’s bus width to (MAX, for this example).  
Therefore, using the information for the HBA in step c above, type the  
following:  
scsi 0/0/10/0/0 width 0  
This changes the HBA’s bus width back to MAX.  
To ensure that the bus width has changed, you can repeat step b to  
display the HBA’s bus width.

Step 2. Find the driver handle designation <drvr_handle>.  
For the A6828A HBA, the <drvr_ handle>designation will be in the DRV  
column that corresponds to the LSI Logic Ultra160 SCSI Driver  
listing in the DRIVER NAMEcolumn.  
In the preceding example, there are two versions of the LSI Logic  
Ultra160 SCSI Driver. The <drvr_handle>designations that  
correspond to the two LSI Logic Ultra SCSI Driversare 20and 21.  
Step 3. Find the controller handle designation, <cntrl_handle>.  
At the EFI Shell prompt, issue the drvcfg command as illustrated in  
the following example:

Drv[2E] Ctrl [2A] Lang [eng]  
Drv[2E] Ctrl [2F] Lang [eng]  
Drv[48] Ctrl [1F] Lang [eng]  
From the output of the drvcfg command, look for the line(s) where the  
NNin Drv[NN]is same as the <drvr_handle>for the driver(s) you are  
using.  
The 2nd column, Ctrl [NN], contains the corresponding <cntrl_handle>,  
where NNis the controller handle. For example, controller handle 1A, 1B,  
1D, 1E, and 23correspond to driver handle 20, and controller handle 22  
corresponds to driver handle 21.  
Step 4. Once the driver handle and the controller handle are identified, the SCSI  
parameters can be displayed and set for any driver and corresponding  
controller (HBA) on the SCSI bus.  
Enter the drvcfg -s <drvr_handle> <cntrl_handle> command at  
EFI shell prompt. The Global Properties screen containing a list of the  
controller (HBA) to which the controller handle corresponds is displayed;  
refer to the following example:

NOTE  
As stated earlier, HP recommends you to always use the A6828A’s  
maximum bus width (16 bits), unless you have Narrow (8-bit) devices on  
the bus and you are experiencing problems with the connection.  
If you decrease the maximum bus width value (16 bits) when the  
transfer rate (MT/sec) is set to 80 or 160, the following message is  
displayed:  
Data Width cannot be set to narrow when MT/Sec is set to 80 or 160.  
Press any key to continue.  
If you want to decrease the maximum bus width value of a particular  
device, first set the transfer rate (MT/sec) to a lower value, and then  
decrease the corresponding bus width value.  
Step 6. After making the necessary changes, press the [ESC] key to exit the  
Device Properties screen. This takes you back to the Adapter Properties  
screen.  
Step 7. Press the [ESC] key to exit the Adapter Properties screen.  
If you did not modify any of the SCSI parameters, then the Global

Installing the A6828A Adapter  
Specifying SCSI Parameters  
Setting SCSI Parameters to Default Values  
You can set the SCSI parameters, except Auto Termination, for the  
adapter to their default values through the BCH menus. The steps you  
follow depend on the type of HP-UX system in which the adapter is  
installed.  
hp servers rp7410, rp8400, and superdome  
On hp servers rp7410, rp8400, and superdome, set the SCSI parameters  
to the default values by performing the following steps:  
Step 1. If you are already at the “Main Menu,” type ser(for “Service Menu”); go  
to step 2.  
If you are not at the “Main Menu,” type main(to return to the “Main  
Menu”), type ser(for “Service Menu”), and then go to step 2.  
Step 2. In the “Service Menu,” type the following command:  
scsi path default  
where, pathis the HBA’s path. This sets all of the SCSI parameters for  
the pathto their default values.  
Step 3. Type mainto get back to the “Main Menu.”  
All Other Servers  
On all servers other than hp servers rp7410, rp8400, and superdome, set  
the SCSI parameters to the default values by following the steps for  
specifying each SCSI parameter (described earlier in this section).  
You will need to know the default value—and how to specify it—for each  
SCSI parameter. To know the valid SCSI parameter values, HP  
recommends you to use the online help for the scsicommand (type  
help scsiwhen you are in the BCH “Service Menu”).  
Chapter 2

Installing the A6828A Adapter  
Installing the SCSI Driver  
Installing the SCSI Driver  
On most of the supported HP-UX PA-RISC systems, the SCSI c720  
driver is used with some of the SCSI interfaces. This driver is  
automatically installed as part of the HP-UX 11.0 core OS and the  
HP-UX 11i base Operating Environment (OE). Therefore, you do not  
have to install it separately.  
However, you must separately install the SCSI c8xxdriver, which is  
used by the A6828A HBA in all the supported HP-UX systems. This  
driver is available in the latest HP-UX bundle or at http://itrc.hp.com.  
TIP  
You should keep in mind that although the installation process installs  
the c8xxdriver, it does not load the c8xxdriver into the HP-UX kernel  
unless it detects one or more SCSI Ultra160 devices installed in the  
HP-UX system. This is done to prevent the kernel from becoming  
unnecessarily large.  
Therefore, if Ultra160 devices (for example, a SCSI Ultra160 “add-in”  
adapter [like the A6828A] or core I/O card) are already installed in the  
HP-UX system, or if you will be installing an Ultra160 add-in adapter  
later through OLA, you should install the c8xxdriver now. If no SCSI  
Ultra160 devices are in the system, and you do not want to install any  
Ultra160 add-in adapters later, do not install the c8xxdriver at this  
time.  
NOTE  
You must install all patches before you install the bundle containing the  
c8xxdriver.  
The following is an overview of the steps you need to perform:  
Step 1. Issue the swlistcommand to see which patches are already installed on  
the system. You can get any patches you need to install from the HP IT  
Resource Center (ITRC) at http://itrc.hp.com.  
If you do not need to install any patches (other than the c8xxbundle), go  
to step 3.

Chapter 2  
 
         
Installing the A6828A Adapter  
Installing the SCSI Driver  
If you need to install one or more patches, go to step 2.  
Step 2. Install any necessary patches.  
Step 3. Follow the normal procedure to install the appropriate software bundle  
for your HP-UX system’s OS or OE.  
Step 4. Issue the swlistcommand to ensure that the necessary patches and the  
c8xxdriver are present.  
Step 5. Check to see if the c8xxdriver is loaded in the kernel by doing one of the  
following two things:  
Use SAM, as follows:  
1. Select the “Kernel Configuration” icon.  
2. Select the “Drivers” icon.  
3. In the “Kernel Configuration” screen, check to see if the c8xx  
driver is in the kernel.  
what /stand/vmunix | grep scsi_c8xx.c  
Check to see if the c8xxdriver is listed.  
If the driver is in the kernel, go to the section, “Configuring LUN 0” on  
page 52.  
If the driver is not in the kernel, go to step 6.  
Step 6. Load the c8xxdriver into the kernel through SAM:  
a. Select the “Kernel Configuration” icon.  
b. Select the “Drivers” icon.  
c. In the “Kernel Configuration” screen, follow the normal steps for  
loading the driver into the kernel (and building a new kernel).  
NOTE  
You need to reboot the system after completing these steps.  
Once you have confirmed that the c8xxdriver is in the kernel, go to  
section, “Configuring LUN 0” on page 52.

Configuring LUN 0  
Configuring LUN 0  
For a disk array that is in a multi-host environment, the SCSI standard  
requires a LUN 0 in certain scenarios:  
If the disk array is connected to the A6828A adapter, and you plan to  
boot from that array, the disk array must be configured as LUN 0. Do  
not configure the LUN with any LUN security (that is, do not restrict  
access).  
HP-UX system that is running from a separate boot disk, the disk  
array must be configured with LUN 0; otherwise, the ioscan  
command will not detect all of the LUNs present in the disk array.  
Once you have determined that LUN 0—if it is required—is configured  
correctly, go to the section, “Verifying Installation” on page 55.

Installing the A6828A Adapter  
Verifying Installation  
Verifying Installation  
After installing the adapter and the c8xxdriver and attaching the  
peripheral devices, verify that all the components are working by  
performing the following steps:  
Step 1. To verify that the adapter is correctly installed, issue the following  
command:  
ioscan -fnk  
The applicable line in the ioscanoutput can have the following form:  
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101  
The third column shows the hardware path of the PCI device/function  
(shown in bold in the above example, for highlighting purposes). The  
A6828A supports one PCI device/function (because it has only one  
channel). In addition, since this is a single channel HBA, one line is  
listed for channel A of the adapter (denoted by a 0as the last digit in the  
hardware path).  
Step 2. In the same line of the ioscanoutput, verify that the adapter is claimed  
by the SCSI c8xxdriver by looking at the fifth column of information  
(shown in bold in the example below, for highlighting purposes).  
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101  
If the adapter is not claimed, see “If the A6828A Adapter is Not Claimed”  
on page 86.  
Step 3. In the same line of the ioscanoutput, verify that the SCSI driver and  
adapter information are displayed (shown in bold in the example below,  
for highlighting purposes).  
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101  
In this example, the SCSI driver information is c8xx(name of the  
driver), and the adapter information is as follows:  
SCSI C1010—The type of HBA (SCSI) and the type of Ultra160  
controller (C1010).  
Chapter 2  
55  
 
               
Installing the A6828A Adapter  
Verifying Installation  
Ultra160—The HBA’s maximum data transfer rate. This can be  
Ultra160, Ultra2, Ultra, Fast, or Async. You should keep the  
following in mind:  
rate set for the HBA.  
— This is either the firmware default or the rate set through the  
BCH menus, unless you attach an SE device, which causes the  
entire bus to change to a transfer rate of Ultra (see “Performance  
Tuning” on page 11).  
Wide—The HBA’s bus width. This can be Wideor Narrow.  
LVD—The HBA’s bus type. This can be LVDor Single-Ended. If no  
bus type is shown, then the SCSI channel is disabled.  
A6828-60101—The HBA’s HP part number.  
Step 4. In addition, in the ioscanoutput, the ctlline shows the adapter’s SCSI  
ID in its hardware path (shown in bold in the example below, for  
highlighting purposes).  
ctl  
0 0/0/10/0/0.7.0 sctl CLAIMED DEVICE  
/dev/rscsi/c0t7d0  
Step 5. Verify that the devices you attached to the adapter are present in the  
ioscanoutput. For example, a partial list may look like this:  
disk 10 0/0/1/0/1.0.0 sdisk CLAIMED DEVICE  
/dev/dsk/c1t0d0 /dev/rdsk/c1t0d0  
disk 11 0/0/1/0/1.2.0 sdisk CLAIMED DEVICE  
SEAGATE ST39103LC  
SEAGATE ST39103LC  
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0

HP 18.2GST318404LC  
/dev/dsk/c9t10d0 /dev/rdsk/c9t10d0  
The second line under each diskline shows the disk’s device files  
(/dev/...[shown in bold in the example above, for highlighting  
purposes]).

Installing the A6828A Adapter  
Verifying Installation  
TIP  
When the system boots after installation, the insfcommand creates the  
proper device files for the “ctl” interfaces (which are usually adapters)  
and the SCSI devices attached to the A6828A adapter. Sometimes,  
though, it does not create all of the needed device files.  
One situation when this happens is when you attach SCSI disks to the  
adapter after the system boots and the adapter is already installed in the  
system.  
In the ioscanoutput, if you see a SCSI device listed without the second  
line, that means you are missing that device’s device files. To fix the  
problem, issue the insf -ecommand, which creates all of the device  
files.  
For more information on the ioscancommand, see the ioscan(1M)man  
page.  
Refer to your system documentation for information on verifying system  
operation.

Installing the A6828A Adapter  
Using the Extended Firmware Interface Flash Utility  
Using the Extended Firmware Interface Flash  
Utility  
If you are installing the A6829A SCSI HBA in an Itanium-based  
system, use the Extended Firmware Interface (EFI) flash utility to verify  
the firmware version, or to flash and save firmware images onto the  
A6829A HBA.  
The EFI flash utility is supported on HP A6829A SCSI HBA, which is  
based on the 53C1010 LSI Logic SCSI chip.  
Features  
The features of the EFI flash utility are as follows:  
Supports HBA selection for updating the SCSI parameters.  
Displays the firmware version on an HBA or in a firmware image file.  
Supports a menu driven mode.  
Allows you to flash the EFI option ROM images.  
Description  
This utility allows you to update the HBA flash memory with the LSI  
Logic EFI driver. New versions of these images are released periodically.  
Your HBA must have a flash memory to use this utility.  
WARNING  
Do not attempt to use this utility to flash any binaries other than  
the EFI option ROM images.  
The executable file name of the EFI utility is EFI8XXFL.EFI. This file,  
and any firmware image files you need, must be stored on a diskette or  
CD-ROM. These files must not be stored on a hard disk, because if the  
flash fails, there is no way to recover these files. Moreover, the hard disk  
may not be accessible.  
58  
Chapter 2  
 
       
Installing the A6828A Adapter  
Using the Extended Firmware Interface Flash Utility  
The EFI utility should be executed from a diskette or CD-ROM. For EFI  
based systems without a floppy diskette drive, burning the EFI utility  
and other firmware images onto a CD-ROM allows proper execution, but  
with reduced functionality. In such a situation, you will not be able to  
save an image of the flash memory to the CD-ROM.  
Preparation  
While booting the EFI enabled systems, the diskette or CD-ROM  
containing the EFI utility needs to be in the drive to allow device  
mapping. The EFI utility and firmware image files are located in the root  
directory or in a subdirectory on the diskette or CD-ROM.  
Boot the system to the EFI shell prompt. The floppy diskette drive or  
CD-ROM drive should appear in the list of mapped devices as fs0.  
In systems with a floppy drive, type fs0at the EFI shell prompt to  
change to this device.  
Menu Driven Mode  
If the EFI utility and firmware image files are located in the root  
directory, enter the efi8xxflcommand at the prompt as illustrated  
below; otherwise, move to the directory in which these files are located  
and continue.

Which chip/adapter (0 to quit)?  
The main window allows you to choose the SCSI chip corresponding to  
the path where you want to perform the selected tasks. Dual channel  
cards display two entries (one for each SCSI chip) on this screen.  
In the aforementioned example, the system has three HBAs - one each on  
the 0x15, 0x3F, and 0x16buses. The HBA on bus 0x3Fis a dual-channel  
HBA (func 0x00 and func 0x01) with flash memory part number  
Am29F010. Since both the channels of a dual channel board share the  
same flash memory, only one of the paths needs to be chosen. If separate  
updates are performed through both the paths, the flash memory is not  
affected.  
NOTE  
Each update overwrites the existing contents of the flash memory.  
The segment value of the HBA corresponding to Choicenumber 5is  
0x01. This indicates that the HBA resides on PCI segment 1. The other  
HBAs reside on PCI segment 0, as the segment value for other HBAs is  
0x00.  
The SYMC1010following LSI Logic, Inc.indicates that the HBAs use  
the 53C1010 LSI SCSI chip, which is supported by this EFI utility.  
If a device does not contain an LSI Logic SCSI chip supported by the EFI  
utility, the lines listing the chip numbers do not appear in the display.  
The HP A6829A SCSI HBA is based on the LSI Logic 53C1010 SCSI  
chip.

General Procedure  
General Procedure  
In general, perform the following steps to troubleshoot the A6828A  
adapter:  
Step 1. Check the connection.  
Ensure that the correct cable is used, connected, and operating properly.  
In addition, ensure that none of the connectors have any bent pins. If you  
do not find any problems with the connection, go to step 2.  
Step 2. Check SCSI bus compatibility.  
Use the commands in the BCH menus to ensure that the data transfer  
rates of the A6828A adapter and the attached devices are compatible  
(see “Setting and Confirming SCSI Parameters” on page 70). If the  
transfer rates of the adapter and attached devices are compatible, go to  
step 3.  
Step 3. Check the adapter.  
Inspect the adapter to ensure that it is seated properly in the PCI slot. If  
necessary, power down the system, reseat the adapter, and restart the  
If a visual inspection of the adapter and cable does not reveal any  
problems, or if an action taken as a result of the inspection does not  
produce a working adapter, go to step 4.  
Step 4. Run the Support Tools Manager (STM) diagnostics application (see  
“Using Support Tools Manager (STM)” on page 85).  
If diagnostics determine that the adapter is defective, you must replace  
it. Contact your local Hewlett-Packard customer representative or call  
the Hewlett-Packard Response Center.

NVRAM SCSI Parameters Do Not Match  
NVRAM SCSI Parameters Do Not Match  
On hp servers rp7410, rp8400, and superdome only, you might see the  
following message after you have installed the A6828A adapter (it would  
be displayed at the BCH “Main Menu”):  
ERROR: PDH NVRAM and I/O card NVRAM SCSI parameters  
do not match for path hw_path  
Search aborted. The SCSI parameters for this card  
must be corrected from the BCH Service menu.  
To correct this problem, follow these steps:  
Step 1. If already at the “Main Menu,” type ser(for “Service Menu”); go to step  
2.  
If not already at the “Main Menu,” type main(to return to the “Main  
Menu”), type ser(for “Service Menu”), then go to step 2.  
Step 2. In the “Service Menu,” type the following command:  
scsi path default  
where pathis the HBA’s path (the hw_pathin the error message).  
This sets all of the SCSI parameters for the pathto their default values,  
which will correct the unmatching SCSI parameters.

Troubleshooting  
Creating Missing Device Files  
Creating Missing Device Files  
When the system boots after installation, the insfcommand creates the  
proper device files for the “ctl” interfaces (which are usually adapters)  
and the SCSI devices attached to the A6828A adapter. Sometimes,  
though, it does not create all of the needed device files. (One situation  
where this happens is when you attach SCSI disks to the adapter after  
the system boots [and the adapter is already installed in the system].)  
The following is an example of what the output of the ioscancommand  
might look like when you issue it to verify the A6828A installation (see  
“Verifying Installation” on page 72):

In the ioscanoutput above, the second line shows the disks’ device files  
(/dev/...[shown in bold in the example above, for highlighting  
purposes]). If you see a disk (or other SCSI devices) listed without the  
second line, that means you are missing that device’s device files. To fix  
the problem, issue the insf -ecommand, which creates all of the device  
files.

Troubleshooting  
If the A6828A Adapter is Not Claimed  
If the A6828A Adapter is Not Claimed  
If the A6828A adapter is not claimed (it shows as “UNCLAIMED” in the  
output from the ioscancommand), the most likely reason is that you  
installed the c8xxdriver but did not install the required patches.  
To fix this problem, perform the following steps:  
Step 1. Confirm that the c8xxdriver has not claimed the A6828A adapter, by  
issuing the following command:  
ioscan -f  
The applicable line in the ioscanoutput could look like this:  
unknown -1 0/0/10/0/0  
UNCLAIMED UNKNOWN  
PCI SCSI (10000021)  
In the example above, the pieces of information that are  
abnormal—indicating an unclaimed adapter—are shown in bold, for  
highlighting purposes. (To see what “normal” output could look like, see  
“Verifying Installation” on page 72 or step 6 below.)  
Step 2. Check to see if the c8xxdriver is loaded in the kernel, by doing one of the  
following two things:  
Use SAM, as follows:  
1. Select the “Kernel Configuration” icon.  
2. Select the “Drivers” icon.  
3. On the “Kernel Configuration” screen, check to see if the c8xx  
driver is in the kernel.  
Issue the following command:  
what /stand/vmunix | grep scsi_c8xx.c  
Check to see if the c8xxdriver is listed.  
If the driver is in the kernel but the A6828A adapter is still not claimed,  
go to step 4.  
If the driver is not in the kernel, go to step 3.  
68  
Chapter 3  
 
           
Troubleshooting  
If the A6828A Adapter is Not Claimed  
Step 3. Load the c8xxdriver into the kernel through SAM by performing the  
following steps:  
a. Select the “Kernel Configuration” icon.  
b. Select the “Drivers” icon.  
c. In the “Kernel Configuration” screen, follow the normal steps for  
loading the driver into the kernel (and building a new kernel).  
Note that you will need to reboot the system as part of these steps.  
Step 4. If the c8xxdriver is in the kernel but the A6828A adapter is still not  
claimed, check the /var/adm/syslog.logfile for errors like these:  
Jan 11 16:08:00 svt38 vmunix: SCSI: SIOP RAM address out of range  
Jan 11 16:12:05 svt38 vmunix: init of hardware not successful. id=10000021 and  
my_isc=24  
If you encounter such errors, you must install the patches required for  
the c8xxdriver. You can find information on the patches you need to  
install in the following places: (1) the README file for the March 2002  
(and later) HWE1100patch bundle (for HP-UX 11.0), and (2) the March  
2002 (and later) HP-UX 11i Release Notes (for HP-UX 11i).  
Step 5. Follow the normal procedure to install the required patches.  
Note that you will need to reboot the system as part of these steps.  
Step 6. After the system reboots, verify that the adapter is now claimed, by  
issuing the following command:  
ioscan -fnk  
The applicable line in the ioscanoutput could look like this:  
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101  
In the example above, the pieces of information that are  
normal—indicating a claimed adapter—are shown in bold, for  
highlighting purposes.  
If the A6828A adapter is claimed, you have fixed the problem.  
If the adapter is still not claimed, repeat steps 2 through 6, as needed.

Setting and Confirming SCSI Parameters  
The SCSI Command  
The SCSI command can be used to display and set SCSI bus parameters  
to ensure that the SCSI adapter is compatible with the SCSI devices.  
Displaying Transfer Rates  
To display the SCSI transfer rate for an adapter using the SCSI  
command, use the following syntax:  
SCSI rate bus_number slot_number  
where  
bus_number  
Specifies the number of the bus on which the adapter is  
installed.  
slot_number  
Specifies the number of the slot the adapter is in.  
For example:  
To display the SCSI transfer rate for an adapter installed on bus 5  
slot 2, issue the following command:  
SCSI rate 5 2  
The command displays the following output:  
PCI device /5.2 = no limit  
To list transfer rates for all the bus and slot numbers, issue the  
following command:  
SCSI rate

Step 2. Find the driver handle designation <drvr_handle>.  
For the A6828A HBA, the <drvr_ handle>designation will be in the DRV  
column that corresponds to the LSI Logic Ultra160 SCSI Driver  
listing in the DRIVER NAMEcolumn.  
In the preceding example, there are two versions of the LSI Logic  
Ultra160 SCSI Driver. The <drvr_handle>designations that  
correspond to the two LSI Logic Ultra SCSI Driversare 20and 21.

Step 3. Find the controller handle designation, <cntrl_handle>.  
At the EFI Shell prompt, issue the drvcfg command as illustrated in  
the following example:  
Shell> drvcfg

Drv[2E] Ctrl [2A] Lang [eng]  
Drv[2E] Ctrl [2F] Lang [eng]  
Drv[48] Ctrl [1F] Lang [eng]  
From the output of the drvcfg command, look for the line(s) where the  
NNin Drv[NN]is same as the <drvr_handle>for the driver(s) you are  
using.  
The 2nd column, Ctrl [NN], contains the corresponding  
<cntrl_handle>, where NNis the controller handle. For example,  
controller handle 1A, 1B, 1D, 1E, and 23correspond to driver handle 20,  
and controller handle 22corresponds to driver handle 21.  
Step 4. Once the driver handle and the controller handle are identified, the SCSI  
parameters can be displayed and set for any driver and corresponding  
controller (HBA) on the SCSI bus.  
Enter the drvcfg -s <drvr_handle> <cntrl_handle> command at  
EFI shell prompt. The Global Properties screen containing a list of the  
controller (HBA) to which the controller handle corresponds is displayed;  
refer to the following example:

Domain Validation  
Domain Validation  
Domain Validation provides a way to automatically detect, and if  
necessary, compensate for hardware that is not performing to the  
optimal level. It does this by reducing the data transfer rate and bus  
width. This allows you to have data integrity even if data transfers  
cannot occur at the maximum data transfer rate supported by the HBA.  
If Domain Validation does reduce the rate and bus width, a message is  
generated so that you can correct the problem.  
Domain Validation is automatically enabled for all SCSI devices on the  
bus, as long as you have set the HBA’s maximum data transfer rate to its  
maximum speed (160 MB/s for the A6828A). See “Maximum Data  
Transfer Rate” on page 45 for more information on setting the HBA’s  
transfer rate.  
TIP  
If necessary, you can disable Domain Validation—if you want to do  
diagnostics, for example—by lowering the transfer rate to less than  
Ultra160 through the commands in the BCH menus (see “Maximum  
Data Transfer Rate” on page 45).  
Domain Validation runs each time the initiator device and target device  
negotiate the transfer rate and bus width. A few things that can cause  
this are as follows:  
A protocol violation or some other exception condition occurs on the  
SCSI bus.  
A SCSI device is powered on and then I/O occurs to that device.  
Things that Domain Validation might detect are as follows:  
Incorrect or improper SCSI bus termination (for example, a missing  
or bad terminator or an incorrect auto termination setting)  
Incorrect hardware configuration  
Cables with the wrong impedance  
Major cable errors (for example, a broken wire within a cable)  
SCSI device spacing problems  
80  
Chapter 3  
 
     
Troubleshooting  
Domain Validation  
Path width errors (for example, a Narrow cable used with a Wide  
SCSI device)  
Damaged or marginal transceivers  
Excessive cross talk  
Excessive system noise  
When Domain Validation determines that communication with the  
target device is not possible at the maximum data transfer rate  
supported by the HBA (Ultra160), it writes the following warning  
message to the /var/adm/syslog.logfile:  
SCSI:Ultra160 SCSI Adapter at hw_path: fallback occurred for  
target target_ID. Possible causes are improper termination,  
improper cabling, or malfunctioning hardware. Verify the  
hardware at the next opportunity.  
Later, it “falls back” (lowers the transfer rate and bus width) by one level,  
according to Table 3-1 below.

NOTE  
The number of entries in Table 3-1 above is subject to change. We are  
providing it here to give you an example of how the fallback procedure  
works.  
As mentioned earlier, Domain Validation tests are run on all targets on  
the SCSI bus, even those targets that do not have Ultra160 capabilities.  
Therefore, the starting point in Table 3-1 depends on the parameters  
that were negotiated for any particular target. In addition, since a SCSI  
bus can contain up to 15 targets, different SCSI parameters might be in  
effect at any one time on the bus (because Domain Validation is running  
on all of the targets at the same time).  
If a fallback does occur and you fix the problem with the target  
hardware, you need to power cycle (power off and then power on) the  
target hardware and then run ioscanwithout the -koption (you can  
specify any other options, though). This restarts Domain Validation for  
that target and restores the negotiated parameters to the highest  
possible transfer rate and bus width. Next, look in the  
/var/adm/syslog.logfile for any new “fallback” warning messages  
82  
Chapter 3  
 
     
Troubleshooting  
Domain Validation  
(shown earlier in this section). If the problem was fixed properly and  
Domain Validation is at the correct level, you will not see any new  
warning messages.  
As an example, if the parameters originally negotiated during the  
normal SCSI initiator/target communications are equivalent to  
Ultra160, but Domain Validation determines that the SCSI bus or the  
target cannot support that data transfer rate, Domain Validation falls  
back to Ultra2 Wide. Later, Domain Validation repeats its test. If the bus  
or target still cannot support the transfer rate, Domain Validation falls  
back another level, to Ultra2 Narrow. As long as failures occur, fallback  
continues, one level at a time, until the last level in Table 3-1  
(Asynchronous) is reached. (Note that a “fallback” warning  
message—shown earlier in this section—is not generated each time  
Domain Validation falls back a level, but only when it successfully settles  
at a level.) If the last level is reached and a failure still occurs, the  
following message is written to the /var/adm/syslog.logfile:  
SCSI:Ultra160 SCSI Adapter at hw_path: Error: The domain  
validation test for target target_ID determined that  
communication may not be possible to this target. Verify the  
hardware at the next opportunity.  
To be able to restore communication to the target hardware, you must fix  
the problem with the target, power cycle (power off and then power on)  
the target, and then run ioscanwithout the -koption to restart Domain  
Validation and renegotiate the parameters for that target. Next, you  
need to check /var/adm/syslog.logfor any new “fallback” warning  
messages. The lack of new “fallback” messages means you successfully  
fixed the problem, and the data transfer rate and bus width are at the  
correct levels.  
Note that when a Domain Validation test succeeds, no message is written  
to the /var/adm/syslog.logfile. The reason is that this would generate  
a large volume of messages, especially on a system that is used heavily.  
Not only would this make the file very large, but the more important  
warning and error messages would not be easy to see.  
In addition, a SCSI selection timeout—when a target device does not  
respond to selection within a certain length of time—will terminate a  
Domain Validation test on a target, and the target will be considered to  
be non-existent. This is so that a bus scan or system boot will not be  
extended by Domain Validation waiting several times for a target that  
does not exist.

Troubleshooting  
Domain Validation  
NOTE  
A Domain Validation test that is terminated for one target does not affect  
the tests being run on any of the other target devices on the SCSI bus.

fastest way for multi-tasking operating  
systems to transfer data.  
device driver A program that allows a  
microprocessor (through the operating  
system) to direct the operation of a  
peripheral device.  
differential A hardware configuration for  
connecting SCSI devices. It uses a pair of  
lines for each signal transfer (as opposed to  
single-ended SCSI, which references each  
SCSI signal to a common ground).

host The computer system in which a SCSI  
host bus adapter is installed. It uses the  
SCSI host bus adapter to transfer  
information to and from devices attached to  
the SCSI bus.  
Domain Validation A software procedure  
in which a host system queries a device to  
determine the device’s ability to  
communicate at the data transfer rate that

pin-1 orientation  
Low Voltage Differential (LVD) A robust  
design methodology that improves power  
consumption, data integrity, cable lengths,  
and support for multiple devices while  
providing a migration path for increased I/O  
performance.  
O
operating system (OS) A program that  
organizes the internal activities of the  
computer and its peripheral devices. An  
operating system performs basic tasks such  
as moving data to and from devices and  
managing information in memory. It also  
provides the user interface.  
M
main memory The part of a computer’s  
memory that is directly accessible by the  
CPU (usually synonymous with RAM).  
P
parity checking A way to verify the  
accuracy of data transmitted over the SCSI  
bus. One bit in the transfer is used to make  
the sum of all the 1 bits either odd or even  
(for odd or even parity). If the sum is not  
correct, an error message appears. SCSI uses  
odd parity for data transfer rates less than  
160 MB/s.  
mainboard A large circuit board that holds  
RAM, ROM, the microprocessor, custom  
integrated circuits, and other components  
that make a computer work. It also has  
expansion slots for host bus adapters and  
other plug-in boards.  
megabyte (MByte) A measure of computer  
storage equal to 1024 kilobytes.  
peripheral component interconnect  
(PCI) A local bus specification that allows  
connection of integrated peripheral  
controller components, peripheral add-in  
boards, and processor/memory systems.  
motherboard See mainboard. In some  
countries, the term motherboard is not  
appropriate.  
multi-tasking The initiation and control of  
more than one sequence of operations. This  
allows programs to operate in parallel.  
peripheral devices A hardware device  
(such as a video monitor, disk drive, printer,  
or CD-ROM) used with a computer and  
under the computer’s control. SCSI  
peripherals are controlled through a SCSI  
host bus adapter.  
multi-threading The simultaneous  
accessing of data by more than one SCSI  
device. This increases the aggregate data  
throughput.  
pin-1 orientation The alignment of pin 1  
on a SCSI cable connector and the pin 1  
position on the SCSI connector into which it  
is inserted. External SCSI cables are keyed  
to ensure proper alignment, but internal  
SCSI ribbon cables might not be.  
N

port address  
port address Also port number. The  
address through which commands are sent  
to a host bus adapter. This address is  
assigned by the PCI bus.  
Reduced Instruction Set Computer  
(RISC) core The HBA’s SCSI chips contain  
a RISC processor, programmed through  
microcode scripts.  
port number See port address.  
S
Processor Dependent Code (PDC) The  
system firmware on HP PA-RISC systems. It  
provides basic read/write capability. Usually  
kept as firmware (ROM based). The system  
firmware on the main board of a computer is  
used to boot and control the system.  
SCSI bus A host bus adapter and one or  
more SCSI peripherals connected by cables  
in a linear chain configuration. The host bus  
adapter can exist anywhere on the chain,  
allowing connection of both internal and  
external SCSI devices. A system can have  
more than one SCSI bus by using multiple  
host bus adapters.  
programmed input/output (PIO) A way  
the CPU can transfer data to and from  
memory via the computer’s I/O ports. PIO  
can be faster than DMA, but requires CPU  
time.  
SCSI device Any device conforming to the  
SCSI standard that attaches to the SCSI bus  
by means of a SCSI cable. This includes  
SCSI host bus adapters and SCSI  
peripherals.  
Q
queue tags A way to keep track of multiple  
commands while allowing increased  
throughput on the SCSI bus.  
SCSI ID A unique identification for each  
SCSI device on the SCSI bus. Each SCSI bus  
has fifteen available SCSI IDs numbered 0  
through 15 for Wide SCSI or 0-7 for 8-bit  
SCSI. The host bus adapter is usually  
assigned ID 7, which gives it priority to  
control the bus.  
R
Random Access Memory (RAM) In  
general, the computer’s primary working  
memory in which program instructions and  
data are stored and are accessible to the  
CPU. Information can be written to and read  
from RAM. The contents of RAM are lost  
when the computer is turned off.  
SCSI-2 The SCSI specification that adds  
features to the original SCSI-1 standard.  
SCSI-3 The current SCSI specification,  
which adds features to the SCSI-2 standard.  
single-ended (SE) SCSI A hardware  
specification for connecting SCSI devices. It  
references each SCSI signal to a common  
ground, as opposed to differential SCSI and  
low-voltage differential SCSI, which use a  
separate return for each signal.  
Read-Only Memory (ROM) Memory from  
which information can be read but not  
changed. The contents of ROM are not  
erased when the computer is turned off.

(SCSI) A specification for a  
V
high-performance peripheral bus and  
command set. The original standard is now  
referred to as SCSI-1.  
VCCI Voluntary Control Council for  
Interference.  
VHDCI Very High Density Cable  
Interconnect.  
synchronous data transfer One of the  
ways data is transferred over the SCSI bus.  
Transfers are clocked with fixed-frequency  
pulses.  
W
Wide SCSI A SCSI-2 feature allowing 16-bit  
transfers on the SCSI bus. This doubles the  
transfer rate over the standard 8-bit SCSI  
bus.  
system firmware Controls the low level  
POST (Power On Self Test) and basic  
operation of the CPU and computer system.  
T
Wide Ultra SCSI The STA (SCSI Trade  
Association) term for SCSI bus width 16 bits,  
SCSI bus speed maximum data rate 40  
MBytes/sec.  
termination The electrical connection  
required at each end of the SCSI bus,  
composed of a set of resistors.  
Wide Ultra2 SCSI The STA (SCSI Trade  
Association) term for SCSI bus width 16 bits,  
SCSI bus speed maximum data rate 80  
MBytes/sec.  
U
Ultra SCSI A standard for SCSI data  
transfers. It allows a transfer rate of up to 20  
MBytes/sec over an 8-bit SCSI bus, and up to  
40 MBytes/sec over a 16-bit SCSI bus. The  
STA (SCSI Trade Association) supports  
using the term “Ultra SCSI” over the older  
term “Fast-20.”  
Ultra160 SCSI (Also called Ultra3 SCSI) A  
standard for SCSI data transfers. It allows a  
data transfer rate of up to 160  
MBytes/second over a 16-bit SCSI bus. The  
bus width is always 16 bits.  
Ultra2 SCSI A standard for SCSI data  
transfers. It allows a transfer rate of up to 40  
MBytes/sec over an 8-bit SCSI bus, and up to  
80 MBytes/sec over a 16-bit SCSI bus. The  
STA (SCSI Trade Association) supports  
using the term “Ultra2 SCSI” over the older  
term “Fast-40.”
