Working with Hot Spares

A hot spare is a disk drive that automatically replaces any failed drive in
a logical drive, and can subsequently be used to rebuild that logical
drive. (For more information on recovering from a disk drive failure,
see
page
147.)

Hot Spare Limitations

You can't create a hot spare for RAID 0 logical drives, simple
volumes, or spanned volumes.
You can't create a hot spare from a disk drive that is already part of a
logical drive.
You should select a disk drive that is at least as big as the largest disk
drive it might replace.

Dedicated Spare or Global Spare?

A global hot spare is not assigned to a specific logical drive and will
protect any logical drive on the controller (except RAID 0 logical
drives). You can designate a global hot spare before or after you build
logical drives on a controller; you can also designate a global hot spare
while you're creating a logical drive. To designate a global hot spare, see
page
91.
A dedicated hot spare is assigned to one or more specific logical drives
and will only protect those logical drives. You must create the logical
drive before you can assign a dedicated hot spare. To assign a dedicated
hot spare, see
