Configuration by N8403-026 RAID Controller
This section describes how to use the internal hard disk drives as RAID System by N8403-026
RAID Controller.
Rebuild
If a HDD is defected, the rebuild feature can recover the data in the defected HDD. The rebuild can
be applied to redundant virtual drives in the RAID1 level.
Manual Rebuild
The manual rebuild can be performed by using Universal RAID Utility, the management utility of
the RAID Controller. Select a HDD and start the rebuild manually.
For the detailed operation, refer to the "Universal RAID Utility Ver2.0 User's Guide" in NEC
EXPRESSBUILDER DVD that comes with the server.
Auto Rebuild
The RAID Controller can automatically start the rebuild without use of any utility such as Universal
RAID Utility.
The auto rebuild includes the following type:
Hot-swap rebuild
Automatic rebuild by hot-swapping defected HDD.
IMPORTANT:
The HDD used for rebuild should have the same capacity, rotation
speed, and standard as the defected HDD.
During rebuild, the processing rate is decreased due to much load.
During rebuild, do not shutdown or reboot the server. If the server is
shutdown by an unforeseen accident such as power interruption,
turn on the power again as soon as possible. The rebuild is
automatically restarted.
The interval from the removal of the defected HDD to the
installation of a substitute HDD should be 60 sec or longer.
If the hot-swap rebuild does not operate, perform the manual
rebuild.
Note the following for the rebuild:
