The following restrictions are imposed for support of the StorageWorks RAID
Array 3000 (RA3000) subsystem:
• The RAID Array 3000 (RA3000) with HSZ22 controller does not
support multi-bus access or multiple-bus failover. You cannot achieve a
no-single-point-of-failure (NSPOF) cluster using an RA3000.
• The KZPBA-CB UltraSCSI host adapter is the only SCSI bus host
adapter supported with the RA3000 in a TruCluster Server cluster. The
KZPBA-CB requires ISP 1020/1040 firmware Version 5.57 (or higher),
which is available with the system SRM console firmware on the Alpha
Systems Firmware 5.4 or later Update CD.
