T o configure a T ruCluster configuration using a DS-DWZZH-05 UltraSCSI hub, follow these steps: 1. Configure and install the DS-DWZZH-05 UltraSCSI hub (Section 2.7.1) 2. V erify that the host adapter termination is installed and cable the host adapter to the DS-DWZZH-05 UltraSCSI hub (Section 2.
• Ensure that no member systems’ host adapter SCSI ID is set at 7 (because the DS-DWZZH-05 uses SCSI ID 7). • Connect a BN38C cable between the host adapter and the appropriate DS-DWZZH-05 UltraSCSI hub port. Each connection forms a SCSI bus segment with the host adapter and the hub.
