Periodically Replacing Hdds - Hitachi HF-W2000 58 Instruction Manual

10.5.3 Periodically replacing HDDs

● Wear cotton gloves when replacing an HDD to prevent problems caused by static electricity.
Not doing so might result in corruption of the data stored on the HDD.
● Verify correct procedures before starting work. Failure to follow the correct procedures might
result in data stored on an HDD being lost.
● Do not use an HDD previously used in any model as a replacement HDD. If you do, this
equipment might not operate properly or the data on the HDDs might be lost because of
configuration information mismatches or other reasons.
● Do not replace two HDDs at the same time. Doing so might result in data corruption.
● When replacing an HDD, set the HDD to offline mode in the Hardware status window, and then
remove the HDD and install the replacement HDD. Installing or removing an HDD when the
hardware status is not verifiable, for example, immediately after the OS starts, might result in a
failure.
An HDD must be replaced periodically. (For information about the recommended replacement cycle, see
APPENDIX HANDLING OF REPLACEABLE COMPONENTS.)
Perform the following procedure for periodic replacement.
Note: The following is the procedure for replacing the HDD installed in drive bay 1. When you are replacing the
HDD installed in drive bay 2, interpret "drive bay 1" as "drive bay 2" and the "DRIVE1 status lamp" as the
"DRIVE2 status lamp" when following the procedure.
(1) Replacing the HDD while the power to the equipment is turned off
1. Back up the data.
2. Shutdown the OS. Unplug the power cord, and wait for at least one minute. Then, replace the HDD installed in
drive bay 1 with a replacement HDD. (See 6.3.6 Installing and removing an HDD or SSD.)
3. Turn on power to the equipment. The RAID1 automatically detects that the replacement HDD is installed and
starts the rebuilding process. Verify that the DRIVE1 status lamp is blinking.
4. The OS starts while the rebuilding process continues. The time required for the rebuilding process depends on
what applications are executed during this period.
If you do not want to start the OS, start the rebuilding process by using the software RAID utility.
5. When the DRIVE1 status lamp turns off, the rebuilding process is complete. In the Hardware status window,
verify that the status of both HDDs is normal.
