I use raidframe with level 5 on a machine in stockholm and it does that
for me.  I haven't played with '1'.  I don't even shut the machine down 
when a drive fails, but then I'm a little more daring.  Replace the disk
with another identical one and then run 'scsictl scan'.

of course, you have to watch the msgbuf to see if a drive has gone bad.
