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 5-1shows 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 -ecommand 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:
