5. Turn on the server, start the SETUP utility, and then specify the boot order from the Boot menu. For
details about the Boot menu, refer to Chapter 2 (1.2.5 Boot) in "Maintenance Guide".
This process is required because the saved boot order is cleared when you remove a Hard Disk
Drive.
6. Refer to Chapter 2 (1.16 Attaching the Front Bezel (Option of R110d-1E)) to put the front bezel back.
Orient the front bezel so that the alignment tab on the left will engage with the server frame and lock it
with the security key.

Replacing a Hard Disk Drive in the RAID System
In the RAID System, you can use the auto rebuild feature to restore data back to the state before a failure
occurred by writing the data saved before the replacement to a new Hard Disk Drive after replacing the
broken Hard Disk Drive.
The auto rebuild feature is enabled in logic drives set to RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50.
The disk is automatically rebuilt when hot swapping (replacing a disk while the power on) a failed Hard Disk
Drive.
During the auto rebuild, the DISK LED on the Hard Disk Drive flashes green and amber alternately to
indicate that the autorebuild is being performed.
Observe the following precautions whenever executing the auto rebuild
• Do not turn off the server until the auto rebuild completes after a Hard Disk Drive fails.
• Leave an interval of at least 90 seconds between a Hard Disk Drive removal and a Hard Disk Drive
installation.
• Do not replace a disk during the auto rebuilding of another Hard Disk Drive (during an auto rebuild, the
DISK LED on the Hard Disk Drive flashes green and amber alternately).
