8.5.3 Performing periodical HDD replacement
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
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. 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
An HDD is a replacement component that must be replaced periodically. (For information
about the recommended replacement cycle, see "APPENDIX HANDLING
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.
 Back up the data.
 Shut down the OS. Unplug the power cable from the outlet, and wait for at least one
minute. Then replace the HDD mounted in drive bay 1 with a replacement HDD. (See
"5.3.5 Installing and removing an HDD".)
 Turn on the power to the equipment. Then the RAID board automatically detects that the
replacement HDD is mounted and starts the rebuild process.
Confirm that the HDD1 status lamp is flashing.
 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.
Therefore, minimize the number of running applications during the rebuild process.
If you do not want to start the OS, while the messages for system initialization are
displayed (during the BIOS memory check), press F2 to launch the BIOS setup menu.
 When the HDD1 status lamp turns off, the rebuild process is complete. Also, in the
Hardware status window, confirm that both HDDs are healthy.
If the BIOS setup menu is started at step , open the upper menu "Exit", move the
cursor to "Save Changes and Exit", and press Enter. A message "Save configuration and
exit?" is displayed. Press Enter to restart the equipment.
