DWZZH 16-Bit UltraSCSI HUB

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.
