Sounds like the 'no boot record' issue. Here's an extract from one of my server change logs, for setting things up *before* they go bad:

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
