Failed Disk Drive Protected by a Hot Spare

When a logical drive is protected by a hot spare, if a disk drive in that logical drive fails the hot
spare is automatically incorporated into the logical drive and takes over for the failed drive.
For instance, when a disk drive fails in the RAID 5 logical drive shown in the next example, the
logical drive is automatically rebuilt (its data is reconstructed) using the hot spare in place of
the failed drive. You can't access the logical drive until the rebuilding is complete.

In this example, the color of the hot spare changed from light-blue to dark-blue, showing
that it is now part of a logical drive.
To recover from the failure:

If copyback is enabled—Data is automatically moved back to its original location once the

Failed Disk Drive Not Protected by a Hot Spare

When a logical drive is not protected by a hot spare, if a disk drive in that logical drive fails,
remove and replace the failed disk drive. The controller detects the new disk drive and begins
to rebuild the logical drive.
If the controller fails to rebuild the logical drive, check that the cables, disk drives, and
controllers are properly installed and connected. Then, if necessary, follow the instructions in
Rebuilding Logical Drives on page
