Array Behavior When a Drive Fails

How an array handles a drive failure depends on whether a spare drive is available and whether the RAID
set containing the failed drive is degraded.
For example:
• If a spare drive is available, the array automatically uses it to replace the failed drive. Performance is
normal after reconstruction completes.
• If a spare drive is not available the RAID set will become degraded (except a RAID 6 set). Performance
may be impaired. A RAID 6 set can survive two simultaneous drive failures.
