HDD Error Recovery (During RAID Operation)

When errors occur during RAID5 or RAID6 operation, the HDD errors in the following table are displayed.

When one HDD has errors ([1down]) in RAID5 mode, the data on the remaining HDDs can be read and recovery is possible. When two HDDs have errors ([2down]) in RAID6 mode, the data on the remaining HDDs can be read and recovery is possible. When any errors occur on an HDD, replace the effected HDD as soon as possible.

For details refer to the operating instructions for the extension unit. *Contact your dealer for information on replacing HDDs.

Important:

RAID5 mode

Data cannot be recovered when two or more HDDs have errors ([2 down]) or when an HDD has errors during recovery.

RAID6 mode

Data cannot be recovered when three or more HDDs have errors ([3 down]) or when an HDD has errors during recovery.
