Dell PowerVault MD3420 - Manual (Page 174)

Parameter Description
NOTE: The physicalDiskCount parameter enables you
to choose the number of physical disks to use in the disk
group. You do not need to specify the physical disks by
enclosure ID and slot ID. The RAID controller modules
choose the specific physical disks to use for the disk group.
diskGroupUserLabel The alphanumeric identifier (including – and _) that you want to
give the new disk group. Enclose the disk group identifier in
double quotes (" ").
raidLevel RAID level of the disk group that contains the virtual disk. Valid
values are 0, 1, 5 or 6.
userLabel Name to give to the new virtual disk. You must put quotation
marks (" ") around the new virtual disk name.
physicalDiskType Specifies the type of physical disk to use in the virtual disk. You
cannot mix physical disk types in the virtual disk. The valid
physical disk type is SAS.
capacity The 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: A space must be added 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 The 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.
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.
segmentSize 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. For information about the segmentSize parameter, see
Using The Auto Configure Command.
enclosureLossProtect Specifies that enclosure loss protection is enforced when
creating the disk group. To enforce enclosure loss protection,
set this parameter to TRUE. The default setting is FALSE. For
