10.1.4.2 Setting the KZPBA-CB SCSI ID

After you determine the console environment variables for the KZPBA-CBs on the shared SCSI bus, use the set console command to set the SCSI ID. For a TruCluster Server cluster, you will most likely have to set the SCSI ID for all KZPBA-CB UltraSCSI adapters except one. If you are using a DS-DWZZH-05 with fair arbitration enabled, you will have to set the SCSI IDs for all KZPBA-CB UltraSCSI adapters.

______________________ Note _______________________

You will have problems if you have two or more SCSI adapters at the same SCSI ID on any one SCSI bus.

If you are using a DS-DWZZH-05, you cannot use SCSI ID 7 for a KZPBA-CB UltraSCSI adapter; SCSI ID 7 is reserved for DS-DWZZH-05 use.

If DS-DWZZH-05 fair arbitration is enabled, the SCSI ID of the host adapter must match the SCSI ID assigned to the hub port. Mismatching or duplicating SCSI IDs will cause the hub to hang.

Use the set console command as shown in Example 10–8 to set the KZPBA-CB SCSI ID. In this example, the SCSI ID is set for KZPBA-CB pkc on the AlphaServer 4100 shown in Example 10–5.
