Array Behavior When a Drive Fails

In firmware version 5.2.5 and later, Dell implemented a copy-to-spare operation to replace failing drives. This

operation can, in many cases, improve the performance of the drive replacement process by avoiding a full

RAID rebuild and as a result can provide better reliability.

If a drive fails, replace it. Do not reinstall it in the array.
