Drive status indicator (PWR LED)

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.
