6.6.3 Defining Hot Spare Drives
Define a hot spare to keep a drive available in your subsystem on which the
RAID controller can automatically start to rebuild information. A hot spare drive
replaces a drive that fails from any drive group on which you created a redundant
logical RAID drive only. The hot spare drive must have a capacity equal to, or
greater than, the failed drive.
Once the controller writes data to a hot spare drive, the status of the hot spare
changes to optimal, and that drive becomes a part of the same drive group from
which a drive failed.
For more information on rebuilding drives, see the section on Rebuilding Drives,
in Chapter 7, which describes each method available.
To define spare drives, follow these steps:
1. Use the up and down arrow keys to highlight the Define Spare option on the
New Configuration menu and press the Enter key. The utility displays the
Define Spare screen as shown in Figure 6–22.
