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 example below, 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.
Disk drive shows
Failed status...
Note: In the example above, 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:
Remove and replace the failed disk drive (following manufacturer's
1
instructions).
If copyback is not enabled—Remove the 'hot spare' designation from
2
the original hot spare (the disk drive that was built into the logical
drive). See page 93
to protect the logical drives on that controller.
If copyback is enabled—Data is automatically moved back to its
original location once the controller detects that the failed drive has
been replaced. No action is required. See
98 for more information.
