Replacement of a faulty hard disk drive in the RAID mode

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).

Note:

Replace the faulty disk immediately and recover data when a single hard disk drive becomes faulty (1 down) even in the RAID

6 mode.

Important:

• Do not turn off the power in the process of recovery. It may result in recovery failure.

Step 1

Remove the hard disk drive whose HDD access indicator is lit or blinking red. Refer to page 53 for how to remove the HDD unit.

Step 2

Install a new HDD unit to the slot from which the faulty disk is removed by referring the disk slot number.

Refer to page 52 for how to install the HDD unit and change the faulty disk.

Step 3

Recognition process and error recovery of the hard disk drive will automatically start.

When the error recovery starts, the HDD access indicator will light orange and red alternately.

(It may appear that the indicator is lighting orange when recovery is being processed at high speed.)

Step 4

When the error recovery is complete, the HDD access indi- cator will go off or light green.

When 2 hard disk drives become faulty (2 down), the data recovery of the second faulty disk will start after completing the data recovery of the first faulty disk.
