Technical data

Make sure that your storage shelves or RAID array subsystems are set up
before completing this portion of an installation.
Use the steps in Table 4–3 to set up a KZPBA-CB for a TruCluster Server
cluster that uses radial connection to a DWZZH UltraSCSI hub.
Table 4–3: Installing the KZPBA-CB for Radial Connection to a DWZZH
UltraSCSI Hub
Step
Action Refer to:
1
Ensure that the eight KZPBA-CB internal
termination resistor SIPs, RM1-RM8 are installed.

Differential Host Adapter
User’s Guide
2
Power down the system. Install a KZPBA-CB
PCI-to-UltraSCSI differential host adapter in
the PCI slot corresponding to the logical bus to
be used for the shared SCSI bus. Ensure that
the number of adapters are within limits for the
system, and that the placement is acceptable.

Install a BN38C cable between the KZPBA-CB
UltraSCSI host adapter and a DWZZH port.

_____________________ Notes _____________________
The maximum length of a SCSI bus segment is 25 meters (82 feet),
including the bus length internal to the adapter and storage devices.
One end of the BN38C cable is 68-pin high density. The other end is
68-pin VHDCI. The DWZZH accepts the 68-pin VHDCI connector.
The number of member systems in the cluster has to be one less than
the number of DWZZH ports.

Power up the system and use the show config
and show device console commands to display
the installed devices and information about
the KZPBA-CBs on the AlphaServer systems.
Look for QLogic ISP1020 in the show config
display and isp in the show device display to
determine which devices are KZPBA-CBs.

Example 4–1 through
Example 4–4
5
Use the show pk* or show isp* console
commands to determine the KZPBA-CB SCSI
bus ID, and then use the set console command
to set the SCSI bus ID.
