Dell 32XX, 34XX, 38XX, 36XX manual Physical disk capacity available in the disk

Parameter	Description
capacity	Size of the virtual disk that you are adding to the
	storage array. Size is defined in units of bytes, KB,
	MB, GB, or TB.
	NOTE: If you do not specify a capacity, all
	physical disk capacity available in the disk
	group is used. If you do not specify capacity
	units, bytes are used as the default. A space
	must be added between the last digit and the
	size (MB, GB, or KB) for values greater than 9.
owner	RAID controller module that owns the virtual disk.
	Valid RAID controller module identifier values are 0
	and 1. The identifier value is 0 for the RAID
	controller module on the top and 1 for the RAID
	controller module on the bottom when viewed
	from the rear of the enclosure. If you do not
	specify an owner, the RAID controller module
	firmware determines the owner.
	NOTE: The owner parameter defines which
	RAID controller module owns the virtual disk.
	The preferred owner of a virtual disk is the
	RAID controller module that currently owns
	the disk group.
cacheReadPrefetch	The setting to turn on or turn off cache read
	prefetch. To turn on cache read prefetch, set this
	parameter to TRUE. To turn off cache read
	prefetch, set this parameter to FALSE.
segmentSize	Amount of data (in kilobytes) 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. For information about the
	segmentSize parameter, see Using The Auto
	Configure Command.
usageHint	The settings for both the cacheReadPrefetch
	parameter and the segmentSize parameter
	should be the default values. The default values are
	based on the typical I/O usage pattern of the
	application that is using the virtual disk. Valid values
	are fileSystem, dataBase, or multiMedia.
dssPreAllocate	The setting to make sure that reserve capacity is
	allocated for future segment size increases. The
	default value is TRUE.
