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.
