Step Action Refer to:

4Update the system SRM console firmware from the latest Alpha Systems Firmware Update CD-ROM.

Use the firmware update release notes (Section 4.2)

______________________ Note _____________________

The SRM console firmware includes the ISP1020/1040-based PCI option firmware, which includes the KZPBA-CB. When you update the SRM console firmware, you are enabling the KZPBA-CB firmware to be updated. On a powerup reset, the SRM console loads KZPBA-CB adapter firmware from the console system flash ROM into NVRAM for all Qlogic ISP1020/1040-based PCI options, including the KZPBA-CB PCI-to-Ultra SCSI adapter.

a If you install additional KZPBA-CB SCSI adapters or an extra network adapter at this time, delay testing the Memory Channel until you have installed all of the hardware.

4.3.1Installation of a KZPBA-CB Using Internal Termination for a Radial Configuration

Use this method of cabling member systems and shared storage in a TruCluster Server cluster if you are using a DWZZH UltraSCSI hub. You must reserve at least one hub port for shared storage.

The DWZZH-series UltraSCSI hubs are designed to allow more separation between member systems and shared storage. Using the UltraSCSI hub also improves the reliability of the detection of cable faults.

A side benefit is the ability to connect the member systems’ SCSI adapter directly to a hub port without external termination. This simplifies the configuration by reducing the number of cable connections.

A DWZZH UltraSCSI hub can be installed in:

•A StorageWorks UltraSCSI BA356 shelf that has the required 180-watt power supply.

•The lower righthand device slot of the BA370 shelf within the RA7000 or ESA 10000 RAID array subsystems. This position minimizes cable lengths and interference with disks.

•A non-UltraSCSI BA356 that has been upgraded to the 180-watt power supply with the DS-BA35X-HH option.

An UltraSCSI hub only receives power and mechanical support from the storage shelf. There is no SCSI bus continuity between the DWZZH and storage shelf.
