HOTSPARE
The HOTSPARE command adds a hot spare drive to spare pool 0 or deletes a hot spare
drive. The capacity of the hot spare drive must be greater than or equal to the capacity of
the smallest drive in the RAID volume. Determine if this is true by using the
DISPLAY
command on the drive.
Observe the following rules when creating hot spare disks:
• You cannot create a hot spare disk unless at least one RAID 1, RAID 10, or RAID
1E volume already exists.
• You cannot create a hot spare and add it to an inactive Integrated RAID volume.
• For HDDs, you cannot add a SAS hot spare disk if the existing volumes on the
controller use SATA disks. You cannot add a SATA hot spare disk if the existing
volumes on the controller use SAS disks.
• For SSDs, you can add a SAS hot spare SSD to a volume with SATA SSDs and you
can add a SATA hot spare SSD to a volume with SAS SSDs, if the Integrated RAID
firmware permits it.
• The maximum permissible number of hot spare drives is two per controller.
• You cannot add an SSD hot spare to a volume that has HDDs, and you cannot add an
HDD hot spare to a volume that has SDDs.
