set dedicated-spare

This command assigns a disk as a Dedicated Hot Spare. A Dedicated Hot Spare is used as a substitute for a disk
that has failed in a specific RAID group. If there are no dedicated hot spares assigned (or available) to a RAID
group, a global hot spare is used. A dedicated hot spare can only be assigned to a single RAID group.
However, one RAID group can have one or more dedicated hot spares.
■ Syntax
set dedicated-spare -disks
■
Parameter
-disks
-rg-number
or
-rg-name
■ Example(s)
The example assigns disk #110 as a dedicated hot spare to the RAID group "R1":
CLI> set dedicated-spare -disks 110 -rg-name R1
The following example assigns disks #110 and #111 as dedicated hot spares to the RAID group named
"RGP001":
CLI> set dedicated-spare -disks 110,111 -rg-name RGP001
The following example assigns two different disks to two different RAID groups. Disk #110 is assigned as a
Dedicated Hot Spare to the RAID group named "RGP1". Disk #111 is assigned as a Dedicated Hot Spare to the
RAID group named "RGP2":
CLI> set dedicated-spare -disks 110,111 -rg-name RGP1,RGP2
In the following example, disk #101 is assigned as a Dedicated Hot Spare. Disk #102 is then added as a
Dedicated Hot Spare to the same RAID group. Adding additional Dedicated Hot Spares does not remove any
hot spares that are previously set:
CLI> set dedicated-spare -disks 101 -rg-name RGP1
CLI> set dedicated-spare -disks 102 -rg-name RGP1

This parameter specifies the disks to be registered as Dedicated Hot Spares. One or more disks
can be specified. If two or more parameters are specified, they must be specified in the same
order as the associated RAID group identifier parameters. For details, refer to
Syntax" (page 19).
This parameter specifies the RAID group identifiers to which the Dedicated Hot Spares will be
