Create RAID Logical Drive (Automatic Drive Select)
This command creates an subsystem across the disk drives in the storage subsystem, and a new logical
drive in the subsystem. The storage subsystem controllers choose the disk drives to be included in the
logical drive.
Syntax
Important: If you have disk drives with different capacities, you cannot automatically create logical
drives by specifying the driveCount parameter. If you want to create logical drives with disk drives of
different capacities, see “Create RAID Logical Drive (Manual Drive Select)” on page 3-93.

Parameters
Parameter Description
driveCount
The number of unassigned disk drives that you want to use in the subsystem.
subsystemUserLabel
The alphanumeric identifier (including – and _) that you want to give the new
subsystem. Enclose the new subsystem name in double quotation marks (" ").
raidLevel
The RAID level of the subsystem that contains the logical drive. Valid values are
0
,
1
,
3
,
5
, or
6
.
userLabel
The name that you want to give to the new logical drive
v
. Enclose the new logical
drive name in double quotation marks (“ ”).
driveType The type of disk drive that you want to use in the logical drive. You cannot mix disk
drive types. Valid disk drive types are
fibre
,
SATA
, or
SAS
.
DriveMediaType
The type of disk drive medium that you want to use for the create RAID logical
drive. Values are
v
HDD – Use this option when you have hard disk drives in the expansion drawer.
v
SSD – Use this option when you have solid state disk drives in the expansion
drawer.
v
unknown – Use if you are not sure what types of disk drive media are in the
expansion drawer.
v
allMedia – Use this option when you want to use all types of disk drive media that
are in the expansion drawer.
Use this parameter only when you use the DriveCount parameter. If you have only
one type of disk drive media, you do not need to use this parameter. You must use
this parameter when you have more than one type of disk drive media in your
storage subsystem.
