Parameter Description
addPhysicalDisks
The setting to add new physical disks to the virtual
disk. For high-capacity expansion enclosures,
specify the enclosure ID value, the drawer ID value,
and the slot ID value for the physical disk. For low-
capacity expansion enclosures, specify the
enclosure ID value and the slot ID value for the
physical disk. Enclosure ID values are 0 to 99.
Drawer ID values are 1 to 5. Slot ID values are 0 to
31. Enclose the enclosure ID value, drawer ID
value, and the slot ID value in parentheses. Use this
parameter with the addCapacity parameter if you
need to specify additional physical disks to
accommodate the new size. This parameter is not
valid for disk pool virtual disks or for thin virtual
disks.
Each disk pool must be created from a minimum
of 11 physical disks specified. There is no upward
limit of physical disks supported in a single disk
pool, but the number cannot exceed the number
of physical disks supported on the storage array.
cacheFlushModifier
The maximum amount of time that data for the
virtual disk stays in cache before the data is flushed
to physical storage. Valid values are listed in the
Notes section.
cacheReadPrefetch
The setting to turn on or turn off cache read
prefetch. To turn off cache read prefetch, set this
parameter to FALSE. To turn on cache read
prefetch, set this parameter to TRUE.
cacheWithoutBatteryEnabled
The setting to turn on or turn off caching without
batteries. To turn on caching without batteries, set
this parameter to TRUE. To turn off caching
without batteries, set this parameter to FALSE.
mediaScanEnabled
The setting to turn on or turn off media scan for
the virtual disk. To turn on media scan, set this
parameter to TRUE. To turn off media scan, set this
parameter to FALSE. (If media scan is disabled at
the storage array level, this parameter has no
effect.)
replicationCacheEnabled
The setting to turn on or turn off the replication
cache. To turn on the replication cache, set this
parameter to TRUE. To turn off the replication
cache, set this parameter to FALSE.
modificationPriority
The priority for virtual disk modifications while the
storage array is operational. Valid values are
highest, high, medium, low, or lowest.
