Appendix A Rebuilding a RAID Volume

If a drive fails, the failure will be indicated by the system fault LED or the Disk Status panel. If a disk drive
fails in a RAID5 volume, first locate the faulty drive in the Disk Status panel, remove the faulty drive with
a drive of the same capacity and rotation speed.
You should be prompted by the message if a hard drive fails or was
removed. An incorrect or abrupt shutdown of the system may also
force the system to rebuild a RAID volume. Data may not have all been
properly distributed to hard drives when inappropirately shut down.
Note that you must carefully identify the faulty drive. Replacing the wrong drive from a RAID5
volume will result in losing 2 member drives. If a RAID5 volume loses 2 members, all data will be
lost on that volume.
