NOTE: You cannot use mixed physical disk types in the same disk group and virtual disk. This command fails if you
specify different types of physical disks for the RAID virtual disk.

Parameters
Parameter Description
physicalDisks Specifies the physical disks to assign to the created
virtual disk. Specify the enclosure ID and slot ID for each
unassigned physical disk to assign to the virtual disk.
Enclosure ID values are
0
to
99
. Drawer ID values are
0
to
4
. Slot ID values are
0
to
31
. You must put parentheses
around the enclosure ID values and the slot ID values.
diskGroupUserLabel The alphanumeric identifier (including – and _) that you
want to give the new disk group. Enclose the disk group
identifier in square brackets ([]).
raidLevel RAID level of the disk group that contains the virtual disk.
Valid values are
0
,
1
,
5
, or
6
.
NOTE: If you set the
raidLevel
parameter to RAID
1, the RAID controller module firmware takes the list
of physical disks and pairs them using the following
algorithm:
Data physical disk =
X
Consistency physical disk =
N
/ 2
+ X
where,
X
goes from 1 to
N
/ 2 and
N
is the number of
physical disks in the list. The following data show an
example of six physical disks and their mirror pairs.
Data Consistency
1
N
/ 2 + 1 = 4
2
N
/ 2 + 1 = 5
3
N
/ 2 + 1 = 6
