This depends on your RAID card. Most RAID cards report the failure of a
drive and will do the rebuilding of a failed drive within the RAID
firmware, outside any OS. So if a drive fails and you replace the drive,
on the next system boot you would have the RAID firmware duplicate the
existing drive to the new drive.
