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 (1 down).
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 (2 down).
When the hard disk drive becomes faulty (down), replace it immediately.
Refer to the operating instructions of the extension unit.
* Contact your dealer about replacement of HDD units.
Important:
• In the RAID 5 mode:
If 2 or more hard disk drives become faulty (2 down) or when another hard disk drive becomes faulty during the data recov-
ery, it is impossible to recover data.
• In the RAID 6 mode:
If 3 or more hard disk drives become faulty (3 down) or when another hard disk drive becomes faulty during the data recov-
ery, it is impossible to recover data.
