When prompted, click Yes to delete the device, or No to cancel the
deletion.

If you click Yes, the logical device is deleted. The disk drives or drive
segments included in the logical device become available, and can be
used to create a new logical drive (see

page 77

), or to expand an

existing logical drive (see

page 84

).

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

page 92
