■ Data recovery (in the RAID 5/RAID 6 mode)

If a hard disk drive failure occurs in the RAID 5 or RAID 6 mode, the error display will appear as shown in the following table.

In the RAID 5 mode, it is possible to read data on the other hard disk drives and recover data even when a single hard disk drive

becomes faulty (1DOWN).

In the RAID 6 mode, it is possible to read data on the other hard disk drives and recover data even when 2 hard disk drives become

faulty (2DOWN).

When the hard disk drive becomes faulty (DOWN), replace it immediately.

Refer also to the operating instructions of the extension unit.

Contact your dealer about purchasing/replacing the hard disk drives.
