Table 9–2: Installing the KZPSA-BB or KZPBA-CB for Radial Connection
to a DWZZH UltraSCSI Hub (cont.)
Step
Action Refer to:
5
Use the show config and show device console
commands to display the installed devices
and information about the KZPSA-BBs or
KZPBA-CBs on the AlphaServer systems. Look
for KZPSA or pk* in the display to determine
which devices are KZPSA-BBs. Look for QLogic
ISP1020 in the show config display and
isp in the show device display to determine
which devices are KZPBA-CBs.
Section 9.1.3 and
Example 9–1 through
Example 9–4
6
Use the show pk* or show isp* console
commands to determine the status of the
KZPSA-BB or KZPBA-CB console environment
variables, and then use the set console
command to set the KZPSA-BB bus speed to
fast, termination power to on, and the KZPSA
or KZPBA-CB SCSI bus ID.

Section 9.1.4.3 and
Example 9–6 through
Example 9–9
_____________________ Notes _____________________
Ensure that the SCSI ID that you use is distinct from all other SCSI IDs
on the same shared SCSI bus. If you do not remember the other SCSI
IDs, or do not have them recorded, you must determine these SCSI IDs.
If you are using a DS-DWZZH-05, you cannot use SCSI ID 7 for a
KZPSA-BB or KZPBA-CB host bus adapter; SCSI ID 7 is reserved for
DS-DWZZH-05 use.
If you are using a DS-DWZZH-05 and fair arbitration is enabled, you
must use the SCSI ID assigned to the hub port the adapter is to be
connected to.
You will have problems, such as not being able to access devices, if
you have two or more SCSI adapters at the same SCSI ID on any one
SCSI bus.
7
Repeat steps 1 through 6 for any other KZPSA-BBs
or KZPBA-CBs to be installed on this shared
SCSI bus on other member systems.

9.1.2 Installing a KZPSA-BB or KZPBA-CB Using External
Termination
Use the steps in Table 9–3 to set up a KZPSA-BB or KZPBA-CB for a
TruCluster Server cluster using the old method of external termination
and Y cables.
