Parameters
Parameter Description
physicalDiskType
Type of physical disks to use for the storage array.
Valid physical disk type is Serial Attached SCSI
(SAS). This parameter is not required if only one
type of physical disk is in the storage array.
raidLevel
RAID level of the disk group that contains the
physical disks in the storage array. Valid RAID levels
are 0, 1, 5 or 6.
diskGroupWidth
Number of physical disks in a disk group in the
storage array. For information about the number of
physical disks that you can use in a disk group, see
Enclosure Loss Protection.
diskGroupCount
Number of disk groups in the storage array. Use
integer values.
virtualDisksPerGroupCount
Number of equal-capacity virtual disks per disk
group. Use integer values.
hotSpareCount
Number of hot spares in the storage array. Use
integer values. For information about hot spares,
see Assigning Global Hot Spares.
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.
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.
securityType
The setting to specify the security level when
creating the disk groups and all associated virtual
disks.
• none—The disk group and virtual disks are not
secure.
• capable—The disk group and virtual disks are
capable of having security set, but security has
not been enabled.
