drive to which it is assigned. An unassigned hot-spare drive is global: it can be
used to rebuild any logical drive on the controller.
Note: You cannot assign a hot-spare drive while a logical drive is being built or
modified (such as a logical drive migration).
1. In the Physical devices view, click
(ready physical drive).
2. Right-click Create assigned hot-spare drive for
the logical device name.
The ServeRAID Manager creates a dedicated hot-spare drive for the logical
drive.

Deleting
a hot-spare drive:
Note: This action is supported on the integrated RAID controller in bootable-CD
mode only.
Use this action to delete a hot-spare physical drive from your configuration.
1. In the Physical devices view, click
(hot-spare drive).
2. Right-click Delete hot-spare drive. The ServeRAID Manager deletes the
hot-spare drive from the configuration by setting the drive state to ready. If you
removed the drive from the server, the ServeRAID Manager removes the drive
from the configuration.
Deleting
a standby hot-spare drive:
Note: This action is not supported on the ServeRAID-8i/8k/8k-l SAS controllers,
the ServeRAID-7t SATA controller, and the integrated RAID controller.
Use this action to delete a standby hot-spare physical drive from your
configuration.
1. In the Physical devices view, click
(standby hot-spare drive).
2. Right-click Delete standby hot-spare drive. The ServeRAID Manager deletes
the standby hot-spare drive from the configuration by setting the drive state to
ready. If you have physically removed the drive, the ServeRAID Manager
removes the drive from the configuration.
Choosing
to create a hot-spare or standby hot-spare drive: Hot-spare drives and
standby hot-spare drives supply additional protection to a RAID configuration. If a
physical drive fails in configurations other than RAID level-0 and RAID level-00,
the hot-spare drive automatically replaces the failed physical drive. Subsequently,
the logical drive can be rebuilt automatically.
Note: You cannot use hot-spare drives with RAID level-0 and RAID level-00.
You can create a hot-spare drive in the Configuration wizard when you first
configure the controller. If you choose not to create a hot-spare drive at that time,
you can do so later.
