CHANGE_INTO_CO

NTAINER

This is an optional switch that changes a vdisk back into an empty container.

NOTE:

Note that the CHANGE_INTO_CONTAINER option (SET VDISK command) will create an empty

container and e

rase any data in the virtual disk.

MIRRORCACHE=

This sets the controller's mirror cache. The values are M IRRORED (ca che is mirrore d between b oth

controllers) and NOTMIRRORED (cache is not mirrored).

NOTE:

For active-active controllers, the only option is MIRRORED. If you try to set to NOTMIRRORED, you

will get an error.

NAME=

This is the new name to give to the speciﬁed virtual disk.

OS_UNIT_ID=

This is the ID t

hat is presented to the host operating system. If set to zero, an ID is not presented to the host.

PREFERRED_PATH=

This is 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 pa th 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 d isks d o 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

This allows

the I/O to be handled by a ny controller.

READ_CACHE

This speciﬁes the reads are satisﬁed from the controller’s cache.

NOREAD_CACHE

This speci

ﬁes the reads are always satisﬁed from media, not the controller’s ca che.

SIZE=

This indicates the new larger size (you c annot change to a size smaller than the original) of the storage in

gigabytes. You can specify size in whole gigabytes only. Fractions are not allowed. The value of SIZE

can be 2 GB through 2000 GB depending on the disk group’s available space.
