10.5 Preventive Maintenance
10.5.1 Creating a Backup Drive
● Wear cotton gloves when replacing a drive in order to prevent failure caused by
static electricity. If you do not, the data stored on the drive 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 drive may be lost.
● If a drive failure prediction icon is displayed as the hardware status in the notification
area of the taskbar, do not use the drive as a backup drive. Failure to heed this
instruction might result in data becoming corrupted or lost.
RAID1 is more reliable compared to a system with a conventional configuration.
Nevertheless, the data stored on the drives may be lost due to human error or other reasons.
If you create a backup drive, you can recover from such data loss. (Note that you can only
restore to the point of backup.) We recommend that you prepare a brand-new drive or
another properly prepared drive for backup and use it to back up the data periodically. Follow
the procedure below, and create a backup drive.
<NOTE>
・When a replacement drive is installed, its capacity must be the same as the
capacity of the drive bay1.
・The following is the procedure for the drive mounted in drive bay 1. When you
make a backup drive from the drive mounted to drive bay 2, interpret drive bay 1
as drive bay 2.
1. Shut down the OS. Unplug the plug of the power cord from the outlet, and wait for at least
one minute. Then replace the drive mounted in drive bay 1 with a replacement drive.
(See "6.3.6 Installing and removing an HDD".)
2. Store the removed drive in a safety place as a backup drive.
3. Turn on the equipment. The RAID controller automatically detects that a new drive has been
installed and starts the rebuild. Confirm that the HDD1 status lamp is flashing.
4. The OS is active during rebuilding. The time required for rebuilding depends on the
applications executed during rebuilding. For this reason, refrain from running applications
until the rebuild finishes. If you do not want to start the OS, turn on the equipment and then,
while the system initialization message is displayed, press the F2 key to launch the BIOS
setup menu.
5. Rebuilding is complete when the HDD1 status lamp turns off. Check the hardware status
window to confirm that both the drives are normal. If you launched the BIOS setup menu in
step 4, open the higher-level menu Exit, move the cursor to Exit Saving Changes,
and then press Enter. The message "Save configuration changes and exit now?" is displayed.
Press Enter to restart the equipment.
