or SCSI bus failure, the host can redistribute the load to the surviving controller. In case of a controller failure, the surviving controller will handle all units.

Partioned storagesets and partitioned
Device partitioning is supported with HSG60 and HSG80 array controllers with ACS Version 8.5.
The following sections describe how to cable the HSZ70 or HSZ80 for TruCluster Server configurations. See Chapter 6 for information regarding Fibre Channel storage.
3.7.1.1Preparing an HSZ70 or HSZ80 for a Shared SCSI Bus Using Transparent Failover Mode
When using transparent failover mode:
•Both controllers of an HSZ70 are connected to the same shared SCSI bus
•For an HSZ80:
–Port 1 of controller A and Port 1 of controller B are on the same SCSI bus.
–If used, Port 2 of controller A and Port 2 of controller B are on the same SCSI bus.
–HSZ80 targets assigned to Port 1 cannot be seen by Port 2.
