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)

Offline

•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.

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 -doption 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.
