RAIDframe doesn't support automatically rebuilding to the hot 
spare, so hot-adding the spare with 'raidctl -a' just before you need 
to rebuild is typically sufficient... (If you have a script to do 
automatic rebuilding in the event of an error, then you can add 
the appropriate 'raidctl -a' command to that script...)

Later...
