Parameter Description
preReadConsistencyCheck
The setting to turn on or turn off preread
consistency checking. Turning on preread
consistency checking verifies the consistency of
RAID redundancy data for the stripes containing
the read data. Preread consistency checking is
performed on read operations only. To turn on
preread consistency checking, set this parameter
to TRUE. To turn off preread consistency checking,
set this parameter to FALSE.
NOTE: Do not use this parameter on non
redundant virtual disks, such as RAID 0 virtual
disks.
readCacheEnabled
The setting to turn on or turn off the read cache.
To turn on the read cache, set this parameter to
TRUE. To turn off the read cache, set this
parameter to FALSE.
consistencyCheckEnabled
The setting to turn on or turn off the write cache.
To turn on the write cache, set this parameter to
TRUE. To turn off the write cache, set this
parameter to FALSE.
segmentSize
The amount of data (in KB) that the RAID controller
module writes on a single physical disk in a virtual
disk before writing data on the next physical disk.
Valid values are 8, 16, 32, 64, 128, 256, or 512
userLabel
The new name that you want to give an existing
virtual disk. Enclose the new virtual disk name in
double quotation marks (" ").
writeCacheEnabled
The setting to turn on write cache capability.
Notes
When you use this command, you can specify one or more of the optional parameters.
You can apply these parameters to only one virtual disk at a time:
• addCapacity
• segmentSize
• userLabel
Add Capacity, Add Physical Disks, And Segment Size
Setting the addCapacity parameter, the addPhysicalDisks parameter, or the segmentSize
parameter starts a long-running operation that you cannot stop. These long-running operations are
performed in the background and do not prevent you from running other commands. To show the
progress of long-running operations, use the show virtualDisk actionProgress command.
