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.
