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
