>Also, RAID is not a backup. RAID provides high(er) availability. You need to have backups still! Absolutely true. In this case we underestimated the workload caused by the service tag and firmware version issues and the fact that the new controller wanted to check and rebuild the array, when the disks themselves should have been fine. In hindsight it might have been faster to reinstall the OS and services plus restore the backups.
