Installing the A7173A Adapter
System Firmware
The firmware on HP 9000 systems is known as Processor Dependent Code (PDC). On HP
Integrity® systems, the system firmware is based on the Extensible Firmware Interface (EFI)
specifications. There is also an EFI driver component of the A7173A adapter firmware for Integrity®
systems.
Processor Dependent Code (PDC) on HP 9000 Systems
PDC is the system firmware on HP 9000 systems. To determine the correct PDC for PA-RISC
based systems,. see the HP Ultra320 SCSI Host Bus Adapter Support Matrix, at:
http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters
The Boot Console Handler (BCH) menus are used offline to confirm the PDC version that is
installed on a PA-RISC based system. See “Using the BCH Menus on HP 9000 Systems” (page 28),
for details.
If you do not have the correct PDC version installed on your system, contact your HP
representative for details on obtaining and installing the correct PDC version.
Extensible Firmware Interface (EFI) on HP Integrity Systems
The system firmware on HP Integrity® systems is based on the Extensible Firmware Interface
(EFI) specifications. An EFI utility can be used offline to verify the system firmware version that
is installed on HP Integrity® systems. See, “Using the EFI Utility on HP Integrity Systems”
(page 32), for details.
See the HP Ultra320 SCSI Host Bus Adapter Support Matrix on http://docs.hp.com to determine
the minimum system firmware version that is needed to use the A7173A adapter on your system.
For a matrix of system firmware for I/O adapters with HP-UX 11i v3 (B.11.31) boot support, as
well as the minimum firmware requirements for HP-UX 11i v3, see the documents at:
http://docs.hp.com/en/hw.html#System%20Firmware

Installing A7173A Adapter Hardware
This section contains information about installing the A7173A adapter hardware in a supported
HP-UX system.
WARNING! The installation procedures in this section require opening the computer cabinet,
which might expose you to high-energy (high-amperage) circuits and sharp edges on the
equipment chassis. Be sure to remove all rings, watches, and other jewelry before opening the
cabinet.
Before beginning 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 HP
if the adapter is damaged.
CAUTION: The A7173A adapter contains electronic components that can easily be damaged
by small amounts 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 Electrostatic Discharge (ESD) kit that is provided with the adapter. Follow the
instructions included with the kit.
• Use a suitable ground; for example, an exposed metal surface on the system chassis can
serve as a ground.
Offline Installation
Install the A7173A adapter in any supported HP-UX system according to the offline host bus
adapter installation procedure for that system. For more information about installation procedures,
see the HP system documentation at:
http://docs.hp.com/en/hw.html
NOTE: The A7173A adapter can be installed in any PCI or PCI-X slot, but for best performance,
HP recommends installing the adapter in a PCI-X, 133 MHz, 64 bit, 4x (“Twin Turbo” or “Dual
Rope”) slot. For more information on slot specifications, see the system documentation; or, for
entry-class servers, see the I/O Slot Matrix – Entry Class Integrity Servers, at:
http://docs.hp.com/en/hw.html#General%20Guides
After installing the A7173A adapter, go to “Connecting SCSI Peripheral Devices” (page 17).
Online Installation
The Online Addition and Replacement feature (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i
v2 and later HP-UX releases) enables you to add or replace PCI host bus adapters without shutting
down and rebooting the system, and without adversely affecting other system components. The
system hardware uses slot-specific power control, combined with HP-UX operating system
support, to enable these features.
16
Installing the A7173A Adapter
For more information on OLAR or OL*, see the following documents:
•
To determine whether OLAR or OL* is supported on your system, see the HP Ultra320 SCSI
Host Bus Adapter Support Matrix:
http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters
•
For detailed instructions on using OLAR on HP-UX 11i v1, see Configuring HP-UX for
Peripherals:
http://docs.hp.com/en/oshpux11i.html#System%20Administration
•
For detailed instructions on using OL* on HP-UX 11i v2, see the Interface Card OL* Support
Guide:
http://docs.hp.com/en/oshpux11iv2.html#System%20Administration
•
For detailed instructions on using OL* on HP-UX 11i v3, see the Interface Card OL* Support
Guide:
http://docs.hp.com/en/oshpux11iv3.html#System%20Administration
IMPORTANT: Superdome systems are not intended for access by users. HP recommends that
Superdome systems only be opened by a qualified HP engineer. Failure to observe this
requirement can invalidate any support agreement or warranty to which the system owner might
otherwise be entitled.
IMPORTANT: If you use OLAR or OL* to add or replace an A7173A adapter, the SCSI ID will
be set at 7 by default. If the SCSI ID for an add-in or replacement adapter needs to be set at some
value other than 7, the mptconfig command can be used to set the SCSI ID after the A7173A
adapter is inserted into the slot and powered on, but before the SCSI cable(s) are connected. See
“About SCSI IDs” (page 24) and “Using mptconfig for Online Configuration” (page 40), for
more information.
Connecting SCSI Peripheral Devices
The A7173A 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 Rules For Connecting SCSI Devices
When you connect SCSI devices to an A7173A or AB290A Host Bus Adapter, the following rules
apply:
•
•
•
•
All of the devices connected to each port must be of the same type; for example, you cannot
mix hard disks and removable-media devices on the same port.
All of the removable-media devices (such as a tape drive, DVD, or CD-ROM) on a SCSI port
must be of the same type and speed. For example, you can connect two or more 320 MB/S
tape drives to a port, but you cannot mix tape drives of different speeds on the same port.
Each SCSI channel on the A7173A adapter has an internal HD (high density) SCSI connector
and an external VHDCI (very high density cable interconnect) SCSI connector. Do not connect
SCSI devices to both the internal and external SCSI connectors on the same channel.
If you connect devices with different data transfer rates to the same SCSI channel, the speed
of that channel will be limited to the maximum transfer rate of the slowest device. For
example, if you connect both LVD SCSI devices and SE SCSI devices to the same SCSI
channel, the data transfer rate for that channel will be limited to 40 MB/s, which is the
maximum rate for SE SCSI.
To view a list of supported peripheral devices see the HP Ultra320 SCSI Host Bus Adapter Support
Matrix:

Connecting Internal Devices
The A7173A adapter has two internal 68 pin HD connectors, one for each SCSI channel. If you
purchased your A7173A adapter as a factory-integrated controller (ordered on product option
0D1), any internal SCSI devices will be connected at the factory. If an internal SCSI device has
been installed on one of the A7173A adapter’s SCSI channels, do not connect any devices to the
external port for that channel.
Connecting External Devices
The A7173A adapter has two external 68 pin VHDCI connectors, one for each SCSI channel.
External SCSI devices, may have 68 pin HD or VHDCI connectors. No SCSI cables are shipped with
the A7173A adapter.
NOTE: Auto termination is factory enabled on the A7173A adapter. External terminators can
be ordered from HP, if necessary (order SCSI LVD/SE terminator: HP product number C2370A).
To connect external SCSI devices to the A7173A adapter:
1.
2.
3.
Plug the 68-pin VHDCI connector on one end of a SCSI cable into an external connector on
the A7173A adapter. Make sure the external connector you attach the SCSI cable to
corresponds to the channel you want to connect the external device to.
Plug the 68-pin HD or VHDCI connector on the other end of the cable into the SCSI connector
on the external SCSI device.
If you need to connect more than one external SCSI device to the adapter, “daisy chain”
them together with shielded external SCSI cables.
When you have finished connecting the external devices, go to, “Setting the SCSI Parameters”
(page 23).

Installing the A7173A Adapter
Confirming the A7173A Adapter Firmware Version
To verify the firmware version currently running on an online A7173A adapter, use the mptutil
<device_file> command. For more information about online and offline firmware verification
or updates, see “Verify or Update A7173A Adapter Firmware On HP 9000 Systems” (page 46),
or “Verify or Update A7173A Adapter Firmware on HP Integrity Systems” (page 46).
To determine the device files for the A7173A adapters in your system, use the ioscan -fnkd
mpt command:

/dev/mpt8, and /dev/mpt9.
When you have determined the device files, use the mptutil <device_file> command to
determine the firmware version currently running (in ROM) on the A7173A adapter. Both channels
on each adapter share the same firmware, so it is only necessary to query one channel to determine
the current firmware version. For example:
# mptutil /dev/mpt8

NOTE:
The In Use Device column only displays on systems running HP-UX 11i v3.
NOTE: When the system boots after installation, the insf command creates the proper device
files for the “ctl” interfaces (which would include the A7173A adapter) as well as the SCSI devices
attached to the A7173A adapter. Sometimes, however, the insf command does not create all of
the device files that are needed. For example, this happens when you attach SCSI disks to the
adapter after the system boots, but the adapter is already installed in the system.
If you see a SCSI device listed in the ioscan output, but there is no device file in the second line
of the ioscsan output for that device, the device file is missing. To solve this problem, use the
insf -e command, which will create all of the device files.
For more information about the ioscan command, see the ioscan(1M) man page.
For more information about the insf command, see the insf(1M) man page.
See your system documentation for information about verifying system operation.
Adding Multi-Initiator Support
The A7173A adapter supports multi-initiator configurations. In a multi-initiator configuration,
multiple SCSI host bus adapters are connected to the same SCSI bus. See “About SCSI IDs”
(page 24), for details on setting SCSI IDs in a multi-initiator configuration.

3 Configuring the A7173A Adapter
This chapter contains the following sections describing configuration of the A7173A adapter:
• “Setting the SCSI Parameters” (page 23)
• “About SCSI IDs” (page 24)
• “About the Maximum Data Transfer Rate” (page 24)
• “About Bus Width” (page 25)
• “About Auto-Termination” (page 26)
• “Configuration Worksheet” (page 27)
• “Setting and Confirming SCSI Parameters Offline” (page 28)
• “Setting and Confirming SCSI Parameters Online” (page 39)
• “Setting SCSI Parameters to Default Values” (page 44)
• “Configuring LUN 0” (page 44)
• “Using the A7173A Adapter as a Boot Device” (page 44)
NOTE: This manual provides installation instructions and technical information for qualified
personnel who maintain or service HP-UX systems. Installing the A7173A adapter requires
proficiency in both hardware configuration and software administration.
Setting the SCSI Parameters
The following user configurable SCSI parameters can be set offline or online:
•
•
•
SCSI ID
Maximum Data Transfer Rate
Bus Width
If the A7173A adapter is new and it is installed in a slot that has never been configured for a
SCSI adapter, the adapter will be set to the following default settings:
•
•
•
SCSI ID = 7
Maximum Data Transfer Rate = MAX (320 MB/s)
Bus Width = 16 bits (Wide)
Even if these default settings are appropriate for your configuration, HP recommends that you
confirm the settings and make changes if necessary.
IMPORTANT: When you replace an A7173A adapter, these conditions determine whether the
previous settings will be applied to the replacement adapter:
•
•
If the replacement adapter is new and has never been installed in a system, then the mpt
driver will continue to use the SCSI parameter settings that are already configured for the
slot.
If the replacement adapter was previously installed in a different slot or system, then the
SCSI parameter settings will not migrate to the new slot or system.
HP recommends that you confirm the settings and make changes if necessary.
The SCSI parameters for A7173A adapters installed in HP 9000 systems can be confirmed or
changed offline using the “SCSI” command, which can be accessed from the Boot Console
Handler (BCH) menus, see “Using the BCH Menus on HP 9000 Systems” (page 28) for details.
Setting the SCSI Parameters
23
NOTE:
The bus width parameter cannot be set offline on rp24xx and rp54xx systems.
The SCSI parameters for A7173A adapters installed in HP Integrity systems can be confirmed
or changed offline using the Extensible Firmware Interface (EFI), see “Using the EFI Utility on
HP Integrity Systems” (page 32).
The SCSI parameters for an A7173A adapter installed in any supported HP-UX system can be
confirmed or changed online using the mptconfig command, see “Using mptconfig for Online
Configuration” (page 40).
To restore the default SCSI parameter settings, see “Setting SCSI Parameters to Default Values”
(page 44).
About SCSI IDs
The firmware suggested default for the A7173A adapter SCSI ID is 7.
You must assign a separate SCSI ID (0 through 15 for a 16-bit SCSI bus) to the A7173A adapter
and to each SCSI device on the bus. The priority of a device on a 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.
HP recommends the A7173A adapter be assigned a higher priority than the other SCSI devices
on the bus. SCSI ID 7 is the preset SCSI ID for the A7173A adapter, 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 HA (High Availability) configuration, multiple SCSI adapters are connected
to the same SCSI bus. In a multi-initiator configuration, the SCSI adapter that carries the most
traffic must be assigned a SCSI ID of 7 (highest priority). The SCSI ID of each of the remaining
SCSI adapters on the bus should be set to the next highest priority remaining SCSI IDs (for
example, 6, 5, 4, and so on) with the highest traffic adapters getting the highest priority SCSI IDs.
Setting SCSI IDs Offline
For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set SCSI IDs offline.
See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.
For HP Integrity® systems, EFI is used to set SCSI IDs offline. See “Using the EFI Utility on HP
Integrity Systems” (page 32), for details.
Setting SCSI IDs Online
The mptconfig command is used to display and set SCSI IDs online for all supported systems.
See “Setting and Confirming SCSI Parameters Online” (page 39), for details.
NOTE: Peripheral device SCSI IDs are typically determined automatically by the storage
enclosure, or they may be set manually by a switch on the storage enclosure. See the
documentation for each peripheral device to determine how to set its SCSI ID.
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 same bus.
About the Maximum Data Transfer Rate
The firmware suggested default for the A7173A adapter data transfer rate is “MAX” or
“NOLIMIT”, which allows a maximum data transfer rate of 320 MB/s. The A7173A can
communicate with all LVD or SE devices that have data transfer rates up to 320 MB/s, including
the following data transfer rates (synchronous communication over a Wide bus):
24
Configuring the A7173A Adapter
•
•
•
•
•
Fast (20 MB/s)
Ultra (40 MB/s)
Ultra2 (80 MB/s)
Ultra160 (160 MB/s)
Ultra320 (320 MB/s)
The actual data transfer rate between the A7173A adapter and the other SCSI devices on the bus
depends on the maximum data transfer rate that is automatically negotiated for each of the
devices on the bus.
For example, if you set the A7173A adapter’s maximum data transfer rate to NOLIMIT (which
will be 320 MB/s), and then connect a disk drive that has a maximum data transfer rate of Ultra2
(80 MB/s), the actual transfer rate will automatically be negotiated to a maximum of 80 MB/s.
WARNING! HP DS2100, DS2110, and DS2300 external storage devices are only supported at
a maximum SCSI data transfer rate of U160. The SCSI data transfer rate must be limited to U160
(or slower) to avoid potential data integrity issues. The SCSI bus will not automatically adjust
to accommodate the DS2100 or the DS2110. The SCSI data transfer rate must be deliberately set
to a maximum of U160; offline via the Boot Console Handler (on HP 9000 systems) or EFI (on
HP Integrity systems), or online via the mptconfig command. With the DS2300 the SCSI data
transfer rate will automatically be negotiated to U160 (or slower), but the negotiation could cause
a few SCSI bus resets, which can be avoided by deliberately setting the maximum SCSI data
transfer rate to U160.
TIP: Unless you are connecting an HP DS2100, DS2110, or DS2300 external storage device to
an A7173A adapter, HP recommends that you always set the A7173A adapter’s maximum data
transfer rate to MAX or NOLIMIT (this is the default setting for the A7173A adapter).
Using MAX or NOLIMIT enables the adapter’s maximum data transfer rate of 320 MB/s to be used,
unless there are slower devices on the bus that automatically negotiate a slower data transfer
rate. Automatic negotiation of the data transfer rate will set the maximum data transfer rate on
the SCSI bus to the maximum data transfer rate capability of the slowest SCSI device on the bus.
TIP: If you are trying to debug a communication problem between the A7173A adapter and a
specific SCSI device, setting the data transfer rate at a slower speed may enhance diagnostic
efforts. See Chapter 5: “Troubleshooting” (page 51), for more information.
Setting the Maximum Data Transfer Rate Offline
For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set the maximum data
transfer rate offline. See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.
For HP Integrity® systems, EFI is used to set the maximum data transfer rate offline. See “Using
the EFI Utility on HP Integrity Systems” (page 32), for details.
Setting the Maximum Data Transfer Rate Online
The mptconfig command is used to set the maximum data transfer rate online for all supported
systems. See “Using mptconfig for Online Configuration” (page 40), for details.
About Bus Width
The firmware suggested default for the A7173A adapter’s bus width is MAX (the A7173A adapter’s
maximum bus width, 16 bits [Wide]). However, either of the following bus widths can be used:
• 8 bits (Narrow)
• 16 bits (Wide)
About Bus Width
25
TIP: HP recommends that you always use the A7173A’s maximum bus width (16 bits), unless
you have Narrow (8-bit) devices on the bus and you are experiencing problems with the
connection.
Setting the Bus Width Offline
For HP 9000 systems, the Boot Console Handler (BCH) menus are used to set bus width offline.
See “Using the BCH Menus on HP 9000 Systems” (page 28), for details.
NOTE:
The bus width parameter cannot be set offline on rp24xx and rp54xx systems.
For HP Integrity® systems, EFI is used to set the bus width offline. See “Using the EFI Utility
on HP Integrity Systems” (page 32), for details.
Setting the Bus Width Online
The mptconfig command is used to set the bus width online for all supported systems. See
“Using mptconfig for Online Configuration” (page 40), for details.
About Auto-Termination
The auto-termination feature on the A7173A adapter ensures the SCSI bus will be properly
terminated in any supported configuration.
The auto-termination state for both of the SCSI channels on the A7173A adapter are factory set
to enable auto termination. HP does not recommend disabling auto termination.
NOTE: All supported configurations require auto termination to be enabled on the A7173A
adapter.

Setting and Confirming SCSI Parameters Offline
If the A7173A adapter is installed in a supported HP 9000 system, use the scsi command,
accessed from the BCH menus, to set or confirm the SCSI parameters offline.
If the A7173A adapter is installed in a supported HP Integrity® system, a menu driven Extensible
Firmware Interface (EFI) utility is available to set or confirm the SCSI parameters offline. See
“Using the EFI Utility on HP Integrity Systems” (page 32).
Using the BCH Menus on HP 9000 Systems
The Boot Console Handler (BCH) consists of a series of menus from which various system
administration tasks can be performed offline on HP 9000 systems. The BCH command syntax
and output are similar, but not identical, across all HP 9000 systems. The examples used in this
document may not be exactly the same as what you see using the BCH menus on your system.
NOTE: For important details about each of the SCSI parameters that can be set offline using
the BCH menus, see:
• “About SCSI IDs” (page 24)
• “About the Maximum Data Transfer Rate” (page 24)
• “About Bus Width” (page 25)
NOTE:
The bus width parameter cannot be set offline on rp24xx and rp54xx systems.
The BCH main menu displays during the boot initialization sequence, after the hardware initializes
on the console, but before the system has booted (provided autoboot is disabled). Example 3-1
shows a typical BCM Main Menu:

Service Menu: Enter command > help scsi
---- SCSI Help --------------------------------------------------------------SCSI displays the SCSI controller parameters. SCSI is also used to set
parameters for a SCSI controller at a specified path. These parameters
are used by the operating system SCSI driver.
If the value of any parameter is not known or cannot be determined, then
a firmware suggested default will be used by the SCSI driver.
An exception is for the termination. If the SCSI card does not support
SCSI Parameters, then the "term" setting will be displayed as UNKNOWN.
In this case, the termination is not programmatically controlled.

To confirm the A7173A adapter’s maximum data transfer rate, follow these steps:
1.
From the BCH Main Menu, enter ser to display the Service Menu.
TIP:
2.
To return to the BCH Main Menu from other BCH menus, enter main.
From the service menu, enter the scsi command, using this syntax:
scsi <path> rate
Where <path> is the path to the A7173A adapter. Example 3-4 shows a typical command
output:

In Example 3-4, the SCSI data transfer rate (SCSI Rate) is MAX. This is the default setting,
which enables the A7173A adapter’s maximum data transfer rate of 320 MB/s.
To retain the current data transfer rate, enter main to go back to the BCH Main Menu.
Setting and Confirming SCSI Parameters Offline
31
To change the data transfer rate, enter the scsi command from the Service Menu, using the
syntax:
scsi <path> rate <rate>
Where <path> is the path to the A7173A adapter, and <rate> is the target rate setting; see the
scsi help screen for acceptable <rate> values for your system. For example, the command
to set the rate for the adapter shown in Example 3-4 to Ultra 160 SCSI would be:
scsi 3/0/6/1/0 rate ULTRA160
The command to set the rate for the adapter shown in Example 3-4 to MAX (320 MB/s) would be:
scsi 3/0/6/1/0 rate NOLIMIT
If you change the data transfer rate, HP recommends that you use the scsi <path> rate
command to confirm that the rate has changed. When you are satisfied that the maximum data
transfer rate is set correctly, enter main to return to the BCH Main Menu.
TIP: Use the scsi command syntax displayed in the scsi help screen to confirm or change
other SCSI parameters.
Using the EFI Utility on HP Integrity Systems
If the A7173A adapter is installed in a supported HP Integrity® system, a menu driven Extended
Firmware Interface based Parallel SCSI Offline Operations Utility (EFI utility) can be used to set
or confirm the SCSI parameters offline. The EFI utility can also be used offline to update the
A7173A adapter firmware, save the A7173A adapter firmware to a file, and view the A7173A
adapter vital product data (VPD). The executable file name of the EFI utility is: pscsi.efi
NOTE: For important details about each of the SCSI parameters that can be set offline using
the EFI utility, see:
• “About SCSI IDs” (page 24)
• “About the Maximum Data Transfer Rate” (page 24)
• “About Bus Width” (page 25)

Setting and Confirming SCSI Parameters Online
The user configurable SCSI parameters can be set or confirmed online on all supported systems
using the mptconfig command.
Setting and Confirming SCSI Parameters Online
39
NOTE: For important details about each of the SCSI parameters that can be set online using
the mptconfig command, see:
• “About SCSI IDs” (page 24)
• “About the Maximum Data Transfer Rate” (page 24)
• “About Bus Width” (page 25)
Using mptconfig for Online Configuration
The mptconfig command has options for changing each of the user-configurable SCSI
parameters. By default, the SCSI ID of the A7173A adapter is “7,” the transfer rate is “ultra320”
and the bus width is “wide.”
To see a help screen showing the mptconfig command syntax, enter mptconfig at the system
prompt with no additional options:
# mptconfig
Usage: mptconfig [options] <dev_file>
<dev_file> = /dev/mptX
Options:
-i initiator_id = 0 to 15
-t target_id
= 0 to 15
-r rate
= ultra|ultra2|ultra160|ultra320
-w width
= narrow|wide
-d set default values for scsi bus
default values are:
initiator_id = 7
rate
= ultra320
width
= wide
Note:
- You must be a privileged user to execute this command. See privileges(5)
for more information on privileged users.
- See mptconfig(1M) for tool details.
To use the mptconfig command you will need to know the device file name for each A7173A
adapter you want to configure. Use the ioscan -kfn command to determine the device file
name for each A7173A adapter installed in your system. Example 3-11 shows a portion of ioscan
-kfn output that includes an A7173A adapter and a disk array that are on the same SCSI bus:

The device files for both channels of an A7173A adapter are listed in Example 3-11. Both channels
of the A7173A adapter share the same PCI slot. Their hardware paths are the same except for
the last digit. In the example, the SCSI channel associated with device file /dev/mpt14 is in use
and is connected to target devices on a SCSI bus. The SCSI channel associated with device file
/dev/mpt15 is not connected to a SCSI bus or to any target devices.
To view a summary of the SCSI parameter settings for a channel on an A7173A adapter, enter
the mptconfig <device_file> command, where <device_file> is the device file name
of an A7173A adapter channel. For example:
# mptconfig /dev/mpt14

Setting the SCSI ID Online
Use the -i option on the mptconfig command to change the SCSI ID of a SCSI initiator. For
example:
# mptconfig -i 6 /dev/mpt14
Confirm: Do you want to change scsi parameters (y/[n]): y
Scan For Devices to avoid id conflict ...
Status ..................................
[Passed]
[Successful]
#
If you attempt to change the SCSI ID to a number that is already in use by another device, the
mptconfig -i command will fail and a message will alert you that the SCSI ID you selected
is already in use.
# mptconfig -i 5 /dev/mpt14
Confirm: Do you want to change scsi parameters (y/[n]): y
Scan For Devices to avoid id conflict ...

Configuring the A7173A Adapter
------------------------------------------------------------------------------
CAUTION: Set the initiator ID on a SCSI adapter carefully. Duplicate SCSI IDs on a SCSI bus
can result in bus hangs, system hangs, and system panics. The mptconfig command will attempt
to verify that no targets are using the specified ID before the change is allowed; however, in the
case of multi-initiator (shared bus) configurations, the mptconfig command cannot detect the
presence of other initiators on the SCSI bus. Use the ioscan command on any servers connected
to the same SCSI bus to verify that the init_id selected is free, before using the mptconfig -i
option.
NOTE:
The In Use Device column is only displayed on systems running HP-UX 11i v3.
Using Common mptconfig Command Line Options
This section lists the mptconfig command line options to change common A7173A SCSI settings
online:
•
Use the -r option on the mptconfigcommand to change the transfer rate for the A7173A
adapter. For example:
# mptconfig -r ultra160 /dev/mpt14
Confirm: Do you want to change scsi parameters (y/[n]): y
Status ..................................
[Successful]
#
•
Use the -w option on the mptconfig command to change the SCSI bus width. For example:
# mptconfig -w narrow /dev/mpt14
Confirm: Do you want to change scsi parameters (y/[n]): y
Status ..................................
[Successful]
#
•
Use the -t option on the mptconfig command to change the SCSI ID of SCSI target devices
that do not automatically configure SCSI IDs.
NOTE: In most cases, target device SCSI IDs are set automatically by the storage enclosure
or by a switch on the storage enclosure. See the documentation for the peripheral device to
determine how to set its SCSI ID.
•
Use the -d option on the mptconfig command to set the SCSI parameters on the A7173A
adapter to the default values. For example:
# mptconfig -d /dev/mpt14
Confirm: Do you want to change scsi parameters (y/[n]): y

Setting SCSI Parameters to Default Values
The default SCSI parameter settings for the A7173A adapter are:
•
•
•
SCSI ID = 7
Maximum Data Transfer Rate = MAX (320 MB/s)
Bus Width = 16 bits (Wide)
•
On HP 9000 systems, the SCSI parameters for the A7173A adapter can be set to the default
values offline, using the SCSI command accessed from the Boot Console Handler (BCH)
menus.
Offline
Depending on the system, the SCSI command may have a “default” option. If there is a
default option, use it. If there is no default option, the SCSI command will have to be issued
for each SCSI parameter that you need to change. See “Using the BCH Menus on HP 9000
Systems” (page 28) for details.
•
On HP Integrity® systems, the SCSI parameters for the A7173A adapter can be set to the
default values offline using the EFI utilities. Each SCSI parameter has to be individually set
to it’s default value. See “Using the EFI Utility on HP Integrity Systems” (page 32), for
details.
Online
Use the mptconfig command -d option to set the SCSI parameters for the A7173A adapter can
be set to the default values online. See “Using mptconfig for Online Configuration” (page 40).
Configuring LUN 0
For a disk array that is in a multi-host environment, the SCSI standard requires a LUN 0 in the
following configurations:
• If the disk array is connected to the A7173A 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).
• If the disk array is connected to an A7173A adapter installed in an 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 is configured correctly (if LUN 0 is required in your
configuration), go to “Verifying the Installation” (page 20), and confirm that all of the components
are working properly.
Using the A7173A Adapter as a Boot Device
If you plan to use the A7173A adapter as a boot device, verify that the correct firmware is installed
on your system. See “System Firmware” (page 15) for details.

4 HP A7173A Administration and Management
This chapter contains the following sections detailing A7173A adapter Administration and
Management tasks:
• “Performance Tuning” (page 45)
• “Online Replacement of the A7173A Adapter” (page 45)
• “Verify or Update A7173A Adapter Firmware On HP 9000 Systems” (page 46)
• “Verify or Update A7173A Adapter Firmware on HP Integrity Systems” (page 46)
• “Using mptutil to Verify or Update A7173A Adapter Firmware” (page 46)
Performance Tuning
To get the best performance from the A7173A adapter, HP recommends the following:
• Increase the number specified for the maximum queue depth:
— HP-UX 11i v1, 11i v2: The scsi_max_qdepth tunable is dynamic, so 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.log file, you can avoid those messages by
reducing the value for scsi_max_qdepth.
— HP-UX 11i v3: The scsi_max_qdepth tunable has been obsoleted and replaced with
the max_q_depth tunable starting with HP-UX 11i v3. The max_q_depth tunable is
dynamic, so no system reboot is needed to change the parameter’s value. You can use
the scsimgr command to set this value at a global level (such as for all disk devices);
for a set of devices (such as for all disk devices from HP); or for a single device (such
as for disk0). See the scsimgr (1M) manpage for details.
•
•
•
•
•
Install the A7173A adapter in a PCI-X, 133 MHz, 64 bit, 4x (“Twin Turbo” or “Dual Rope”)
slot.
Do not connect any Single Ended (SE) SCSI devices on the same SCSI bus with Low Voltage
Differential (LVD) SCSI devices. This limits the maximum bus speed to Ultra SCSI (40 MB/s).
See “Important Rules For Connecting SCSI Devices” (page 17).
When you assign SCSI IDs to SCSI devices on the bus, assign the highest priority SCSI IDs
to the devices with the highest volume of data transfer; see “About SCSI IDs” (page 24).
Set the A7173A adapter’s maximum data transfer rate to the optimal setting for your
configuration; see “About the Maximum Data Transfer Rate” (page 24).
Make sure you have the correct SCSI hardware configuration. Domain Validation can detect
some configuration problems; see “Domain Validation” (page 53).
Online Replacement of the A7173A Adapter
Online Addition and Replacement (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i v2 and later
HP-UX releases) enables you to add, replace, or delete a PCI host bus adapter in an HP-UX system
without shutting down or rebooting the system, and without adversely affecting other system
components. The system hardware uses slot-specific power control combined with HP-UX
operating system support to enable this feature. For more information, see “Online Installation”
(page 16).
Performance Tuning
45
IMPORTANT: If the replacement A7173A adapter is new, meaning that it has never been installed,
the mpt driver will continue to use the SCSI parameter settings that are already configured on
the slot.
If the A7173A adapter has been previously installed in a different slot or system, the SCSI
parameter settings will not migrate to the new slot or system.
In either case, it is still strongly recommended that the SCSI parameter settings be confirmed,
and changed if necessary. See “Setting the SCSI Parameters” (page 23) for details.
Verify or Update A7173A Adapter Firmware On HP 9000 Systems
On HP 9000 systems, the A7173A adapter firmware cannot be verified or updated offline. The
A7173A adapter firmware version can only be verified or updated online, using the mptutil
command. See “Using mptutil to Verify or Update A7173A Adapter Firmware” (page 46).
Verify or Update A7173A Adapter Firmware on HP Integrity Systems
On HP Integrity® systems, the A7173A adapter firmware has two components:
•
SCSI firmware
— To verify or update the SCSI component of the A7173A adapter firmware online, see
“Using mptutil to Verify or Update A7173A Adapter Firmware” (page 46).
— To verify or update the SCSI firmware component of the A7173A adapter firmware
offline, see “Downloading and Installing a Firmware Image” (page 36).
•
EFI driver
— The EFI Driver component of the A7173A adapter firmware can be updated offline
only.
— To verify the EFI driver component of the A7173A adapter firmware online, see “Using
mptutil to Verify or Update A7173A Adapter Firmware” (page 46). The EFI driver
component of the A7173A adapter firmware cannot be updated online.
— To verify or update the EFI driver component of the A7173A adapter firmware offline,
see “Downloading and Installing a Firmware Image” (page 36).

The device file for each channel of an A7173A adapter is in the second line of the ioscan
output. In Example 4-1, /dev/mpt14 and /dev/mpt15 are the device files for the two
channels of the A7173A adapter installed in the PCI slot located at hardware path 1/0/14/0.
2.
Use the mptutil command to determine the SCSI firmware version running (in ROM) on
the A7173A adapter. Both channels on each A7173A adapter share the same SCSI firmware,
so it is only necessary to query one channel to determine the SCSI firmware version installed
on both channels.
The version of the EFI driver component of the A7173A adapter firmware will also be
displayed. Example 4-2 shows the command output for a typical system:

Use the -d option of the mptutil command to update the SCSI firmware on the A71713A
adapter. The command syntax is:
mptutil -d <firmware_image> <device_file>
where <firmware_image> is the name of the SCSI firmware image file you want to flash
to ROM on the A7173A adapter, and <device_file> is the device file name for one of the
channels on the A7173A adapter. Since both channels on an A7173A adapter share the same
ROM, the SCSI firmware image can be flashed to ROM via either channel.
In Example 4-3, SCSI firmware image 1.03.35.69 IO is flashed to the A7173A adapter associated
with the /dev/mpt14 device file:

5 Troubleshooting
The A7173A adapter is a single field-replaceable unit (FRU) and does not contain any
field-serviceable parts. Troubleshooting procedures described in this chapter are limited to
verifying that the adapter is operational and that a valid connection is established.
This chapter contains the following sections describing how to troubleshoot the A7173A adapter:

“Contacting Your Hewlett-Packard Representative” (page 63)
General Troubleshooting Procedure
Follow these steps to troubleshoot the A7173A adapter:
1.
Check the connection.
Verify that the correct cables are used, that none of the connectors have any bent pins, and
that the cables are securely connected. If you do not find any problems with the connections,
go to step 2.
2.
Check SCSI bus compatibility:
• If your system is running online, use the mptconfig command to ensure that the data
transfer rates of the A7173A adapter and all attached devices are compatible. See “Setting
and Confirming SCSI Parameters Online” (page 39).
• If you have an HP 9000 system and the system is offline, use the commands in the BCH
menus to verify that the data transfer rates of the A7173A adapter and all attached
devices are compatible. See “Using the BCH Menus on HP 9000 Systems” (page 28).
• If you have an HP Integrity system and the system is offline, use the EFI utilities to
verify that the data transfer rates of the A7173A adapter and all attached devices are
compatible. See “Using the EFI Utility on HP Integrity Systems” (page 32).
If the transfer rates of the adapter and attached devices are compatible, go to step 3.
3.
4.
5.
Confirm that your system has the correct system firmware (PDC or EFI) version installed;
see “System Firmware” (page 15). If the correct system firmware version is installed, go to
step 4.
Confirm that the correct A7173A adapter firmware version is installed; see “Confirming the
A7173A Adapter Firmware Version” (page 19). If the correct A7173A adapter firmware
version is installed, go to step 5.
Check the adapter installation.
Inspect the adapter to make sure it is seated properly in the PCI slot. If necessary, power
down the system, reseat the adapter, and restart the system.
If a visual inspection of the adapter and cables 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 6.
General Troubleshooting Procedure
51
6.
7.
Confirm that the correct disk device firmware version is installed on your hard disks. You
can obtain disk firmware updates from the ITRC web site (http://itrc.hp.com). Search for
the model number of the disk drive(s) that you want to update. Installation instructions are
provided in the firmware download package.
Run the Support Tools Manager (STM) diagnostics application (see “Using Support Tools
Manager (STM)” (page 61)).
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.
Creating Missing Device Files
When the system boots after installation, the insf command automatically creates the proper
device files for the “ctl” interfaces, including the A7173A adapter and the SCSI devices attached
to it. Under certain conditions, though, the insf command does not create all of the necessary
device files. For example, this can occur if you attach additional SCSI disks to an A7173A adapter
that is already installed in a system that is up and running.
Example 5-1 shows part of a typical ioscan command output, as it could appear when verifying
the A7173A installation (see “Verifying the Installation” (page 20)):

In Example 5-1, the second line of each disk entry shows the device file for that disk, in the
format /dev/dsk/cxtxdx [...]. If you see a disk or other SCSI device listed without the
second line, then its device files are missing.
To correct this problem, use the insf -e command to create all of the device files. Then use the
ioscan command again to confirm that the device files have been created.
The A7173A Adapter Is Claimed, But There Is No IO
If the A7173A adapter is claimed, but there is no IO, follow these steps to diagnose the problem:
NOTE: Use the iostat command to determine whether there is active IO. See the iostat
manpage for more information.

Use the ioscan -fnkd mpt command to determine the device file of the controller.
Use the mptutil <dev_file> command to display information about the controller.
Examine the “Chip Information” section of the mptutil output to determine if the driver
state is “operational.”
If the driver state is not operational, examine the mptutil command output to determine
the A7173A adapter firmware version; then confirm that it is current. To determine the
recommended adapter firmware version, see the HP Ultra320 SCSI Host Bus Adapter Support
Matrix at:
http://docs.hp.com/en/netcom.html#SCSI%20Host%20Bus%20Adapters

Troubleshooting
5.
If the A7173A adapter firmware is not current, install the latest firmware, see “Using mptutil
to Verify or Update A7173A Adapter Firmware” (page 46).
a. Use the mptutil <dev_file> command to display information about the controller.
b. Examine the “Chip Information” section of the mptutil output to determine if the
driver state is “operational.”
6.
If the driver state is still not operational, or if the firmware did not require an update, then
the card may be faulty. Contact your HP support representative.
No Target Devices are Displayed in the ioscan Output
If the A7173A adapter is claimed, but no target devices are displayed in the ioscan output,
check the system log (syslog) for error messages from the mpt driver. The error messages may
provide some clues about the source of the problem. For information on how to view the system
log, see the syslogd(1M) manpage.
Confirm SCSI Parameters
You can ensure compatibility between the SCSI controller and SCSI devices using the commands
available for setting and displaying the appropriate SCSI bus parameters, including the SCSI
IDs.
There are separate procedures for setting and confirming the SCSI parameters offline and online.
See Chapter 3: “Configuring the A7173A Adapter” (page 23), for details.
Domain Validation
Domain Validation automatically detects, and if necessary, compensates for hardware that is
not performing at the optimal level. It does this by reducing the data transfer rate and bus width.
This maintains data integrity, even if data transfers cannot occur at the maximum data transfer
rate supported by the adapter. If Domain Validation reduces the transfer rate and the bus width,
a message is generated to alert you to the problem.
Domain Validation is automatically enabled for all SCSI devices on the bus, as long as the adapter’s
maximum data transfer rate is set to 160 MB/s or higher. See “About the Maximum Data Transfer
Rate” (page 24), for more information on setting the adapter’s transfer rate.
Domain Validation runs each time the initiator and target devices negotiate the transfer rate and
bus width. Events that can cause Domain Validation to run are:
• A protocol violation or some other exception condition that occurs on the SCSI bus
• A SCSI device that is powered on, and then I/O occurs to that device
Table 5-1 shows the types of problems that Domain Validation can detect:
Table 5-1 Problems Detected By Domain Validation
Problem
Possible Cause
Incorrect SCSI bus termination
A missing or bad terminator, or an incorrect auto termination setting.
Incorrect hardware configuration
Cables with the wrong impedance
An incorrect cable type.
Major cable errors
A broken wire within a cable, or a bad connector.
SCSI device spacing problems
Path width errors
For example Narrow cable used with a Wide SCSI device.
Damaged or marginal transceivers
No Target Devices are Displayed in the ioscan Output
53
Table 5-1 Problems Detected By Domain Validation (continued)
Problem
Possible Cause
Excessive cross talk
Poor shielding or grounding.
Excessive system noise
Poor shielding or grounding.
When Domain Validation determines that communication with the target device is not possible
at the maximum data transfer rate supported by the adapter (Ultra320), it writes a warning
message to the /var/adm/syslog.log file. Example 5-2 shows a typical log entry:
Example 5-2 Typical Domain Validation syslog Entry
SCSI Ultra320 0/3/1/1 instance 9:
Domain Validation forced SCSI Parameter fallback.
Target ID 2 - Currently operating at Ultra160 Wide.
The data transfer rate then “falls back” by one level to a slower setting. Table 5-2 lists the fallback
levels for most systems:
Table 5-2 Domain Validation Fallback Levels

NOTE: The number of entries in Table 5-2 is subject to change. It is provided here to give you
an example of how the fallback procedure works.
Domain Validation tests are run on all targets on the SCSI bus, even those targets that do not
have Ultra320 capabilities. The starting point in Table 5-2 depends on the parameters that were
negotiated for any particular target. Since a SCSI bus can contain up to 15 targets, several different
SCSI parameters may be in effect at any one time on the bus, because Domain Validation is
running on all of the targets at the same time.
For example, if the parameters originally negotiated during the normal SCSI initiator/target
communications are equivalent to Ultra320, but Domain Validation determines that the SCSI
bus or the target cannot support that data transfer rate, then Domain Validation falls back to
Ultra160. After the fallback, Domain Validation repeats its test. If the bus or target still cannot
support the transfer rate, Domain Validation falls back another level, to Ultra2 Wide; then to
Ultra2 Narrow, and so forth. As long as failures occur, fallback continues, one level at a time,
until the lowest level in Table 5-2 (Asynchronous) is reached. Note that Domain Validation does
not generate a fallback warning message such as Example 5-2 (page 54) each time that it falls
back a level, but only when it successfully settles at a level. If a failure occurs at the lowest level,
the device is taken offline and a Domain Validation failure message is written to the
/var/adm/syslog.log file. For example:
54
Troubleshooting
SCSI Ultra320 0/3/1/1 instance 9:
Domain Validation failed, device offline.
Target ID = 2.
Restoring Performance After A Domain Validation Fallback or Failure
First, you must fix the problem with the target hardware that caused the fallback. See Table 5-1
(page 53) for a listing of the types of problems that Domain Validation can detect.
When you have corrected the problem, use the mptutil -t tgt_reset [target_id]
command to restart Domain Validation for the specified target, and restore the negotiated
parameters to the highest possible transfer rate and bus width. Then check the
/var/adm/syslog.log file for any new fallback warning messages, such as Example 5-2
(page 54). If the problem is fixed properly and Domain Validation is at the correct level, no new
warning messages will be present.
If a device has failed all fallback tests and is offline, follow these steps to restore communication
to the target hardware:
1.
2.
3.
4.
5.
Fix the problem with the target.
Run mptutil with the-t tgt_reset option.
Power cycle the target (power off and then power on).
Run ioscan without the -k option to restart Domain Validation and renegotiate the
parameters for the target.
Check /var/adm/syslog.log for any new fallback warning messages.
The absence of new fallback messages indicates that the problem is fixed, and the data transfer
rate and bus width are at the correct levels.
NOTE: When a Domain Validation test succeeds, no message is written to the
/var/adm/syslog.log file. The reason is that this would generate a large volume of messages,
especially on a system that is used heavily. This would make the file very large, and more
important warning and error messages would not be as easy to see.
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 a bus scan or system boot will not be extended by Domain
Validation waiting several times for a target that does not exist.
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.
Using the mptutil Command
The mptutil command is a diagnostic tool for Ultra320 SCSI controllers claimed by the mpt
driver. You can use mptutil to view configuration information, issue task management
commands, and read or reset accumulated statistics for the A7173A adapter and connected target
devices. The mptutil command can also be used to update the A7173A adapter firmware; see
“Using mptutil to Verify or Update A7173A Adapter Firmware” (page 46).
A specific device file corresponding to a single channel on an A7173A adapter is necessary to
use the mptutil command. Each device file represents a single channel on the A7173A adapter.
Commands issued through mptutil are channel specific and do not affect the whole adapter
(except for firmware downloads). Some mptutil command options are intended for use by HP
support personnel, and require detailed knowledge of the Ultra320 SCSI driver or firmware to
interpret the output.
To see a help screen showing the mptutil command syntax, enter mptutil at the system
prompt with no additional options:

Using Support Tools Manager (STM)
STM is a software application that you can run from the console to obtain status and descriptive
information about the A7173A adapter. STM can also be used to diagnose problems.
NOTE: You must use STM version C.46.00 or later with the A7173A adapter for HP-UX 11i v3
(February 2007).
For more information about STM and other online diagnostic tools, see the documents at:
http://docs.hp.com/en/diag.html#2%20Online%20Diagnostics
HP Event Monitoring Services (EMS)
Event Monitoring Service (EMS) notifies a system administrator when an event occurs on the
system.
Using Support Tools Manager (STM)
61
A hardware event monitor monitors the hardware for unusual behavior (known as an event)
and sends a message to EMS, which notifies the system administrator and provides suggestions
for correcting the problem.
There is a disk monitor that will monitor all disks attached to the A7173A adapter.
For more information about EMS and other online diagnostic tools, see the documents at:
http://docs.hp.com/en/diag.html#2%20Online%20Diagnostics
HP Offline Diagnostics Environment (ODE)
The A7173A adapter supports HP’s Offline Diagnostics Environment (ODE). ODE is an offline
support tools platform for troubleshooting systems that are running without an operating system
or systems that cannot be tested using online tools. The offline environment is also useful for
testing that needs to be done before a system is booted.
ODE provides a user-friendly interface for diagnostics and utilities that have been developed to
run in this environment.
The Offline Diagnostics Environment has a distributed architecture consisting of several modules.
Each module has a specific function and uses well defined protocols to communicate with the
other modules.
You can use ODE with either a command line interface, or a menu-driven interface. The command
line interface enables you to select specific tests and utilities to perform on a specific hardware
module. The menu-driven interface enables you to specify the hardware module to be tested,
then automatically selects and performs the necessary tests.
The Offline Diagnostic Environment consists of:
•
•
•
A Test Controller, which acts as the user interface and launches the execution of the Test
Modules.
Test Modules, which consist of diagnostic or utility programs designed to execute within
ODE. These modules exercise or diagnose user specified hardware units.
A System Library (SysLib), which consists of a set of common routines for use by both the
Test Controller and the Test Modules. These routines perform I/O, string parsing, and system
control.
For more information about ODE, see the documents at:
http://docs.hp.com/en/diag.html#3%20Offline%20Diagnostics
PCI Error Recovery
The PCI Error Recovery feature provides the ability to detect, isolate, and automatically recover
from a PCI error, avoiding a system crash. PCI Error Recovery is included with the HP-UX 11i
v3 operating system, and it is enabled by default.
NOTE: PCI Error Recovery is not supported on all platforms. To determine if PCI Error Recovery
is supported on your system, see the PCI Error Recovery Support Matrix:
http://www.docs.hp.com/en/ha.html#PCI%20Error%20Recovery
With the PCI Error Recovery feature enabled, if an error occurs on a PCI bus containing an I/O
card that supports PCI Error Recovery the following events occur:
•
•
The PCI bus is quarantined to isolate the system from further I/O and prevent the error from
damaging the system.
The PCI Error Recovery feature will attempt to recover from the error and reinitialize the
bus so I/O can resume.
If the PCI Error Recovery feature is disabled and an error occurs on a PCI bus, a Machine Check
Abort (MCA) or a High Priority Machine Check (HPMC) will occur, and the system will crash.
62
Troubleshooting
For more information about PCI Error Recovery, see the documents at:
http://www.docs.hp.com/en/ha.html#PCI%20Error%20Recovery
Contacting Your Hewlett-Packard Representative
If the equipment is covered by an HP service contract, document the problem as a service request
and forward it to your HP representative. Include the following information where applicable:
• Describe the problem, including the events and symptoms leading up to the problem.
Attempt to describe the source of the problem.
Include commands, communication subsystem commands, functionality of user programs,
result codes and messages, and data that can reproduce the problem.
•
Obtain the version, update, and fix information for all software. To check the version of the
kernel, issue this command:
uname -r
To check patches, issue the following command:
what /stand/vmunix | grep scsi
This allows HP to determine if the problem is already known and the correct software is
installed at your site.
•
•
•
•
•
•
•
Illustrate the context of messages as clearly as possible. Record all error messages and
numbers that appear at the user terminal and the system console.
Prepare the formatted output and a copy of the log file for the HP representative to analyze.
Prepare a listing of the HP-UX I/O configuration being used for the HP representative to
analyze.
Try to determine the general area within the software where the problem might exist. See
the appropriate reference manual and follow the guidelines on gathering information for
that product.
Document your interim (workaround) solution. The cause of the problem can sometimes
be found by comparing the circumstances in which the problem occurs with the circumstances
in which the problem does not occur.
In the event of a system failure, obtain a full memory dump.
If the directory /var/adm/crash exists, the HP-UX utility /sbin/savecore automatically
executes during reboot to save the memory dump. HP recommends that you create the
/tmp/syscore directory after successfully installing this product. Send the output of the
system failure memory dump to the HP representative.
If the equipment is not covered by an HP service contract, a charge for time and materials might
be necessary.

A SCSI Sense Codes
SCSI Status Codes, Sense Keys, and Sense/Qualifier Code Pairs
This appendix contains tables listing SCSI Status Codes, SCSI Sense Keys, and a partial list of
the most common SCSI Additional Sense Code/Qualifier Code Pairs. This information is used
to interpret SCSI error messages.
Example A-1 shows a typical SCSI error message:

Additional Sense and
Qualifier, without
interpretation.
The status and sense key are interpreted for you in the error message text. Table A-1: “SCSI Status
Codes (complete list)” (page 65) and Table A-2: “SCSI Sense Keys (complete list)” (page 66)
provide a complete listing of the SCSI Status Codes and the SCSI Sense Keys.
Each Additional Sense and its corresponding Qualifier Code require interpretation on your part.
Use the two codes together to determine their meaning from Table A-3: “Most Common SCSI
Additional Sense Code/Qualifier Pairs” (page 66).
In Example A-1, the Additional Sense Code (0x29) and Qualifier Code (0x02) together mean:
“SCSI bus reset occurred.”
Table A-3 (page 66) lists the most common Additional Sense Code/Qualifier Code Pairs. For a

ground).
direct memory
access (DMA)
A method of moving data from a storage device directly to RAM, without using the CPU’s
resources.
DMA bus master
A feature that allows a peripheral to control the flow of data to and from system memory by
blocks, as opposed to PIO (Programmed I/O), where the flow is byte by byte.
Domain

PCI bus assigns an IRQ path for each SCSI host bus adapter.
K
KByte (kilobyte)
A measure of computer storage equal to 1024 bytes.
L
logical unit

operating system performs basic tasks such as moving data to and from devices and managing
information in memory. It also provides the user interface.
P
parity checking
A way to verify the accuracy of data transmitted over the SCSI bus when CRC is not used. 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.
peripheral
component
interconnect (PCI)
