automatically uses them to rebuild failed disks.

Description

Automatic
Rebuild

If you have configured hot spares, the RAID controller automatically tries to use them to
rebuild failed disks. Select Objects

Physical Drive to display the list of physical drives

while a rebuild is in progress. The hot spare drive changes to REBLD A[array number]-
[drive number], indicating the hard drive is being replaced by the hot spare. For example,
REBLD A01-02 indicates that the data is being rebuilt in array 1 on hard drive 2.

Manual
Rebuild

Manual rebuild is necessary if no hot spares with enough capacity to rebuild the failed
drives are available.You must insert a drive with enough storage into the subsystem
before rebuilding the failed drive.

The CU allows manual rebuild for an individual drive or a group of drives. Rebuilding a
group of drives is done through the batch mode. Use the following procedures to rebuild
a failed drive manually in individual or batch mode.
