I should add that, with a tested boot-from-alternate disk in place
I've been able to avoid the boot into rescue mode procedure, thus
minimizing down time.  Ignoring the case of hot-swap devices and
hot spares:

   - shut down system
   - remove faulty disk
   - add in replacement disk
   - reboot to normal run level (3 or 5).  RAID is now running in 
     degraded mode, but you're back in operation
   - do disk paritioning, MBR init, and reconstruction while in service
