10.5.3 Performing Periodical HDD Replacement
NOTICE
●
Wear cotton gloves when replacing an HDD in order to prevent failure caused by
static electricity. If you do not, the data stored on the HDD may get corrupted.
●
Make sure you check the correct procedure before you start the work. If you do
not follow the correct procedure, the data stored on the HDD may be lost.
●
As a replacement HDD, do not use an HDD previously used in the A model or
the B model. If you do, this equipment may not operate properly or the data on
the HDDs may be lost because of configuration information mismatches, or
other reasons.
●
Do not replace the two HDDs at the same time. If you do, the data gets
corrupted.
●
When you replace an HDD, make sure that you set the HDD into the offline
mode in the
Hardware status
window, and then remove that HDD and mount
the replacement HDD. If you mount or remove an HDD when the hardware
status cannot be checked, for example, immediately after the OS starts, a
failure may result.
An HDD is a replacement component that must be replaced periodically. (For information about
the recommended replacement cycle, see "APPENDIX HANDLING REPLACEABLE
COMPONENTS ".)
Follow the procedure below for periodic replacement.
Note: The following is the procedure for replacing the HDD mounted in drive bay 1. When you
replace the HDD mounted in drive bay 2, interpret drive bay 1 as drive bay 2 and the
HDD1 status lamp as the HDD2 status lamp when following the procedure.
(1) If you replace the HDD while the power to the equipment is turn off
1. Back up the data.
2. Shut down the OS. Unplug the plug of the power cord from the outlet, and wait for at least
one minute. Then replace the HDD mounted in drive bay 1 with a replacement HDD. (See
"6.3.7 Installing and removing an HDD".)
3. Turn on the power to the equipment. Then the software RAID automatically detects that the
replacement HDD is mounted and starts the rebuild process. Confirm that the HDD1 status
lamp is flashing.
4. The OS starts while the rebuild process is continuing. The time required for the rebuild
process depends on what applications are executed during this period.
If you do not want to start the OS, start the rebuild process using the software RAID utility.
5. When the HDD1 status lamp turns off, the rebuild process is complete. Also, in the
Hardware status
window, confirm that both HDDs are healthy.
