RAID MODE FAULT TOLERENCE
RAID 0
If any of the drives fail all, the data will be lost. There is
NO
redundancy in RAID 0. Replace the failed drive and reset the RAID
mode.
RAID 1, 10, 3, and 5
If one drives fails, the data can be rebuilt. The XD5 will begin the
rebuild mode automatically if a spare drive is installed or the XD5 will
begin the rebuild mode when the failed drive is replaced.
Clear RAID (JBOD)
If any of the drives fail, only the data on the failed drive will be lost,
none of the other drives are affected. Replace the failed drive and
format the new drive.
REBUILD
RAID Rebuild with Spare Drive
If your RAID configuration is RAID 1, RAID 10, RAID 3 (3 or 4 drives)
or RAID 5, (3 or 4 drives) there is at least one spare drive slot that
can be use for a spare auto-rebuild drive.
To configure the RAID with a spare auto-rebuild drive, first configure
the RAID mode. Once the RAID mode has been configured, install a
spare drive in the next unused drive slot.
NOTE:
The spare drive must be equal to or larger than the largest
drive in the array. The spare does not need to be formatted. The
spare drive should be erased, any data on the spare drive will be lost
when rebuild begins.
Should a drive fail or become degraded, the XD5 alarm will sound
beep
and the LED of the faulty drive will flash red. Press the
SET
button
to turn off the alarm. The RAID array will start rebuilding
automatically using the installed spare auto-rebuild drive.
The rebuild is complete when the spare drive stops flashing red and
turns blue.
