Dell 36XX, 34XX, 38XX Add Capacity, Add Physical Disks, And Segment Size, PreReadConsistencyCheck

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.
