6. Reboot the RaQ 4.
7. If you have added a second hard disk drive to a RaQ 4i server, add the new
storage unit through the browser-based UI. See “Storage” on page 82.
If you have replaced a failed hard disk drive in a RaQ 4r server, you do not
need to add the new hard disk drive through the UI. When rebooting, the
system automatically detects the new hard disk drive.
The RaQ 4r automatically synchronizes the new hard disk drive to the
existing hard disk drive so that the server will be able to provide disk
mirroring (RAID-1).
Opening the RaQ 4
1. Power down the RaQ 4. See “Powering down” on page 155.
2. Unplug the RaQ 4 from the power supply.
3. Remove the power cord from the rear of the RaQ 4. The cable is located
beside the power switch. See Figure 2 on page 5.
4. Unscrew the top cover. Ten screws hold the top cover in place. The screws
are labeled 1 through 10 in Figure 59 on page 162.
✍
Note: During the synchronization process, the RaQ 4r cannot
provide disk mirroring but it can still serve requests.
Warning: You must power down the RaQ 4 before opening the unit.
✍
Note: If the RaQ 4 is mounted on an equipment rack, remove the
RaQ 4 from the rack and take it to a service area. Do not attempt
this upgrade while the RaQ 4 is still in the equipment rack.
