10.1.4.3 Setting KZPSA-BB SCSI Bus ID, Bus Speed, and Termination Power

If the KZPSA-BB SCSI ID is not correct, or if it was reset to 7 by the firmware update utility, or you need to change the KZPSA-BB speed, or enable termination power, use the set console command.

______________________ Note _______________________

All KZPSA-BB host bus adapters should be enabled to generate termination power.

Set the SCSI bus ID with the set command as shown in the following example:

>>>set pkn_0_host_id #

The n specifies which KZPSA-BB the environment variables apply to. You obtain the n value from the show device and show pk* console commands. The number sign (#) is the SCSI bus ID for the KZPSA.

Set the bus speed with the set command as shown in the following example:

>>>set pkn0_fast #

The number sign (#) specifies the bus speed. Use a 0 for slow and a 1 for fast.

Enable SCSI bus termination power with the set command as shown in the following example:

>>>set pkn0_termpwr on

Example 10–9 shows how to determine the present SCSI ID, bus speed, and the status of termination power, and then set the KZPSA-BB SCSI ID to 6 and bus speed to fast for pkb0.

Example 10–9: Setting KZPSA-BB SCSI Bus ID and Speed

P00>>> show pkb*

pkb0_fast 0 pkb0_host_id 7 pkb0_termpwr on

P00>>> set pkb0_host_id 6

P00>>> set pkb0_fast 1

P00>>> show pkb0_host_id

6

P00>>> show pkb0_fast

1
