I think our system goes into 'degraded' mode when no spare is present.

I'm the degenerate.

(some mail misaddresses running around.)

Not quite. A failed disk will send the system into 'degenerated' mode if there is no spare present. The system will shut down after 24 hours in degenerated mode as a failsafe. However, if a spare disk *is* present, the system goes into 'reconstruction' mode and rebuilds the failed disk. Once reconstructed the system is back up and running as usual with no threat of a failsafe shutdown. If you have 2 hot spare disks, and one is used to rebuild a failed disk, then you will have one spare disk remaining.

Is it true that when one HD goes bad, it will be reconstructed on the hotspare, but if you don't pull out bad HD and replace it within the 24 hours system will shutdown? What happens in a case if you have 2 hotspare?

Thanks, --Leila.
