DWZZH 16-Bit UltraSCSI HUB
3–2 EK–DWZZH–UG. D01
This type of configuration would prevent systems with different SCSI IDs from
accessing disks ‘belonging to’ a particular SCSI ID, which promotes data
security between servers on a shared SCSI bus; however, it does not prevent
SWCC from performing tasks on those disks. In other words, if you set up the
SWCC client to have configuration capability (see SWCC documentation) then
you can access everything in the storage subsystem, regardless of HSZ70 access
ID restrictions.
For further information on setting up and configuring agents on HSZ controllers,
please see the SWCC and controller documentation.
