6. 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.
7. 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)):
Example 5-1 Typical ioscan Listing of SCSI Devices
disk 10 0/0/1/0/1.0.0 sdisk CLAIMED DEVICE SEAGATE ST39103LC
/dev/dsk/c1t0d0 /dev/rdsk/c1t0d0
disk 11 0/0/1/0/1.2.0 sdisk CLAIMED DEVICE SEAGATE ST39103LC
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0
disk 45 0/2/1/0/1.8.0 sdisk CLAIMED DEVICE HP 18.2GST318404LC
/dev/dsk/c9t8d0 /dev/rdsk/c9t8d0
disk 46 0/2/1/0/1.10.0 sdisk CLAIMED DEVICE HP 18.2GST318404LC
/dev/dsk/c9t10d0 /dev/rdsk/c9t10d0
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.
1. Use the ioscan -fnkd mpt command to determine the device file of the controller.
2. Use the mptutil <dev_file> command to display information about the controller.
3. Examine the “Chip Information” section of the mptutil output to determine if the driver
state is “operational.”
4. 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:
