Recovery of RAID5 Disk
Replacing and recovering RAID5 disk
When an HDD access indicator on the front panel of the
extension unit is lit red, it indicates that the hard disk drive
malfunctions.
Do the following to replace and recover the faulty hard disk.
Important:
• Immediately replace the hard disk when an HDD
access indicator is lit red. If one indicator is lit red and
the other blinks red, or the second hard disk fails during
the recovery process, it is impossible to recover the
data as a RAID5 system.
• When the ERROR indicator is lit red, it is a system error.
Consult your dealer. Refer to Troubleshooting.
• Refer to
■
Replacing/Mounting HDD for details on
types, mounting positions, and number of hard disk dri-
ves that should be installed in the unit.
1 SAFETY MODE ON
Select ON for "HDD Safety Mode" and close the SETUP
MENU.
→
The recorder will restart and the HDD SAFETY MODE
window will be displayed.
2 Replacement
• Confirm that the HDD POWER indicator on the front
panel of the extension unit went out.
• Replace the faulty hard disk referring to
■
Replacing/Mounting HDD.
• Go to the next step below after finishing the con-
nection of the front cover harness with the unit while
the switches and buttons remain operable (step 11
of
■
Replacing/Mounting HDD).
3 Data Recovery
1 Confirm that the MODE switch is set to RAID5.
2 While holding down the RECOVER button, press the
RESET button.
3 While holding down the RECOVER button, release
the RESET button about 1 second later.
4 Release the RECOVER button after the HDD
POWER indicator turns on (5 seconds later).
5 Repeat the above steps when initializing two or
more units.
→
The HDD access indicator of the drive will blink red
and orange alternately during the recovery process
and will go out when the process is completed
Notes:
• For reference, it will take about 12 hours to complete
the recovery process for 160 GB data.
• Do not operate any switch or button of the extension
unit while the HDD indicator of the drive in the recovery
process blinks red and orange alternately. Otherwise,
the process will fail.
• The recorder can be operated during the data recovery
process, though the recovery time will be lengthened.
