HSZ70 controller A and controller B
HSZ80 controller A Port 1 (2) and controller B Port 1 (2)
___________________ Note ___________________
You must use the same port on each HSZ80 controller.
3. Install the DS-DWZZH-03 or DS-DWZZH-05 UltraSCSI hub in a
DS-BA356, BA356 (with the required 180-watt power supply), or BA370
storage shelf (see Section 3.6.1.1 or Section 3.6.1.2)
4. If you are using a:
DS-DWZZH-03: Install a BN37A VHDCI to VHDCI cable between
the trilink connector on controller A (HSZ70) or controller A Port 1
(2) (HSZ80) and any DS-DWZZH-03 port. Install a second BN37A
cable between the trilink on controller B (HSZ70) or controller B
Port 1 (2) (HSZ80) and any port on the second DS-DWZZH-03.
DS-DWZZH-05:
Verify that the fair arbitration switch is in the
Fair position to
enable fair arbitration (see Section 3.6.1.2.2)
Ensure that the W1 jumper is removed to select wide addressing
mode (see Section 3.6.1.2.3)
Install a BN37A cable between the DWZZH-05 controller port
and the open trilink connector on HSZ70 controller A or HSZ80
controller A Port 1 (2)
Install a second BN37A cable between the second DWZZH-05
controller port and the open trilink connector on HSZ70
controller B or HSZ80 controller B Port 1 (2)
5. When the KZPBA-CBs are installed, use a BN38C (or BN38D) HD68
to VHDCI cable to connect the first KZPBA-CB on each system to a
port on the first DWZZH hub. Ensure that the KZPBA-CB SCSI ID
matches the SCSI ID assigned to the DWZZH-05 port it is cabled to
(12, 13, 14, and 15).
6. Install BN38C (or BN38D) HD68 to VHDCI cables to connect the second
KZPBA-CB on each system to a port on the second DWZZH hub. Ensure
that the KZPBA-CB SCSI ID matches the SCSI ID assigned to the
DWZZH-05 port it is cabled to (12, 13, 14, and 15).
Figure 37 shows a two-member TruCluster Server configuration with
a radially connected dual-redundant HSZ70 configured for multiple-bus
failover.
