You may have problems if the member system supports the bus_probe_algorithm console variable and it is not set to new. See Section 2.3.2.
The KZPBA-CB UltraSCSI host adapter:
•Is a high-performance PCI option connecting the PCI-based host system to the devices on a 16-bit, ultrawide differential SCSI bus.
•Is a single-channel, ultrawide differential adapter.
•Operates at the following speeds:
–5 MB/sec narrow SCSI at slow speed
–10 MB/sec narrow SCSI at fast speed
–20 MB/sec wide differential SCSI
–40 MB/sec wide differential UltraSCSI
______________________ Note _______________________
Even though the KZPBA-CB is an UltraSCSI device, it has an HD68 connector.
Use the steps in Table 10–2 to set up a KZPSA-BB or KZPBA-CB host bus adapter for a TruCluster Server cluster that uses radial connection to a DWZZH UltraSCSI hub with an HSZ40 or HSZ50 RAID array controller.
