SSSU Command Reference

NOMIRRORED_WRITEBACK

No writes are stored in mirrored caches. After the data is stored in one cache, the write is complete. The write is complete even if a mirror copy of the cache is not available.

OS_UNIT_ID=

The ID that is presented to the host operating system. If set to zero, no ID is presented to the host.

PREFERRED_PATH=

The preferred controller path that is specified to handle all I/O for the virtual disks. If a controller fails, the path always reverts to the working controller.

■PATH_A_BOTH—Controller path A fails over to controller B. When controller A restarts, the virtual disks fail back to controller A. This is failover/failback mode.

■PATH_A_FAILOVER—Controller path A fails over to controller B. When controller A restarts, the virtual disks do not fail back over to controller A. This is failover-only mode.

■PATH_B_BOTH—Controller path B fails over to controller A. When controller B restarts, the virtual disks fail back to controller B. This is failover/failback mode.

■PATH_B_FAILOVER—Controller path B fails over to controller A. When controller B restarts, the virtual disks do not fail back over to controller B. This is failover-only mode.

NOPREFERRED_PATH

Allows the I/O to be handled by either controller.

READ_CACHE

Reads are satisfied from the controller’s cache.

NOREAD_CACHE

Reads are always satisfied from the physical disks, not the controller’s cache.

REDUNDANCY=

The amount of data protection set when creating the virtual disk. If not specified, the default is Vraid0.
