9.5.3.1 Replacing an HDD in RAID1 while the Equipment power is off

To replace an HDD in RAID1 while the Equipment power is off, follow the procedure below.
Note: The procedure below exemplifies how to replace the HDD installed in drive bay 1.
When you replace the HDD installed in drive bay 2, read "drive bay 1" and "HDD1 status
lamp" in the procedure below as "drive bay 2" and "HDD2 status lamp".
1. Back up the data.
2. Shut down the OS, disconnect the power cord plug from the outlet, and wait at least one
minute. Then, replace the HDD in drive bay 1 with a new HDD according to
Subsection 5.4.3, "Detaching/attaching hard disk drive (HDD)."
3. Turn on the Equipment by connecting the power cord plug to the outlet and pressing the
Power switch on the front panel. The RAID controller automatically detects mounting of
the new HDD and starts the RAID1 rebuilding process. Ensure that the HDD1 status
lamp blinks.
4. Along the progress of the rebuilding process, the OS starts up. Time required for the
rebuilding process depends on what application programs are running during the process.
Accordingly, it is suggested that you do not run any application program until the
rebuilding process is complete.
Note: If you do not want to start up the OS, activate the BIOS setup menu by pressing
the F2 key while the system initialization message (BIOS memory check) is displayed or
when the digital LED for status indication shows "C0". In the background, the
rebuilding process continues. Let it run to completion for about 70 minutes on a 160GB
HDD.
5. When the rebuilding process is complete, the blinking HDD1 status lamp goes off. Open
the "Hardware status" window from the task tray icon, and ensure that the status of each
HDD in RAID1 configuration is shown "Healthy" in this window.
Note: If you activated BIOS setup menu in step 4, ensure completion of the rebuilding
process with turning off of the HDD1 status lamp. Then, select Exit in the BIOS setup
menu, point to Exit Saving Changes, and hit the Enter key. Respond to the "Save
configuration changes and exit now?" message dialog by hitting the Enter key to restart
the Equipment.
