Dell PowerVault MD3260i - Manual (Page 168)

Parameter Description
NOTE: You can use any combination of alphanumeric
characters, hyphens, and underscores for the names.
Spaces are not allowed. Command names can have a
maximum of 30 characters. If you exceed the
maximum character limit, replace square brackets
([ ]) with angle brackets (< >) to overcome this
limitation.
freeCapacityArea Index number of the free space in an existing disk group to
use to create the new virtual disk. Free capacity is defined
as the free capacity between existing virtual disks in a
disk group. For example, a disk group might have the
following areas: virtual disk 1, free capacity, virtual disk 2,
free capacity, virtual disk 3, free capacity. To use the free
capacity following virtual disk 2, specify:
freeCapacityArea=2
Use the show diskGroup command to determine if the
free capacity area exists.
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: Add a space between the last digit and the size
(bytes, KB, MB, or GB) for values greater than 9. If
you do not specify a capacity, all the available
physical disk capacity in the disk group is used. If you
do not specify the capacity unit, bytes is used as the
default unit.
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
RAID controller module ownership 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
