Step Action Refer to:
4 Update 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.
4.3.1 Installation 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.
