NAS-7400 Responds to a Critical RAID Volume
How the NAS-7400 responds to a Critical RAID Volume depends on the RAID
level of your Volume and whether you have a spare drive available:

For a RAID 1 Volume or a three-drive RAID 5 Volume, if a spare
drive is available, the RAID Volume begins rebuilding itself
automatically.

For RAID 1, 5, and 10 Volumes, when no spare drive is available,
you must replace the failed disk drive. The RAID Volume will begin
rebuilding itself when you install the new disk drive.

RAID 0 Volumes go offline after a disk drive failure. A RAID 0
Volume cannot be rebuilt. All data on the Volume is lost.
Additional Details about Rebuilds

The Rebuild takes several minutes, depending on the size of your
disk drives.
