Dell PowerVault MD3260i - Manual (Page 309)

Parameter Description
virtualDisk The World Wide Identifier (WWID) of the virtual disk for
which you are setting properties. You can use the WWID
instead of the virtual disk name to identify the virtual disk.
Enclose the WWID in angle brackets (< >).
addCapacity The setting to increase the storage size (capacity) of the
virtual disk for which you are defining properties. Size is
defined in units of bytes, KB, MB, GB, or TB. The default
value is bytes. This parameter is not valid for thin virtual
disks.
NOTE: The maximum capacity is 250 GB.
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.)
