I have an IBM System X server with a ServerRaid M5014 controller. Drives 0 and 1 are RAID1 and contain the OS. The remaining 4 drives are RAID5 and were recently upgraded to larger drives. That means I have 4 old hard drives laying around. Can I simply replace the bad hard drive with one of these old drives and rebuild it or will the fact that the old drive was formerly part of a RAID5 array make that impossible.
