General Troubleshooting Procedure

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.

Check SCSI bus compatibility:

If the transfer rates of the adapter and attached devices are compatible, go to step 3.

Confirm that your system has the correct system firmware (PDC or EFI) version installed; see “System Firmware”. 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”. 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.

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)”).

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.
