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).

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

6 mode.

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

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.

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.

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.)

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.
