Configuring Your Server 4-29
Configuration by Internal RAID Controller
This section describes how to use the internal hard disk drives as RAID System by Internal RAID
Controller (equivalent to N8103-116).
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 disks in the RAID1, RAID5, or RAID6 level.
Manual Rebuild
The manual rebuild can be performed by using Universal RAID Utility, the management utility of
the Internal RAID Controller (equivalent to N8103-116). Select a HDD and start the rebuild
manually.
For the detailed operation, refer to the "Universal RAID Utility
User's Guide" in NEC
EXPRESSBUILDER DVD that comes with the server.
Auto Rebuild
The Internal RAID Controller (equivalent to N8103-116) can automatically start the rebuild without
use of any utility such as Universal RAID Utility.
The auto rebuild includes two types as follows:
Standby rebuild
Automatic rebuild by using hot-spares. In the configuration including hot-spares, the
rebuild is performed automatically if a HDD assigned to a virtual disk is defected.
Hot-swap rebuild
Automatic rebuild by hot-swapping defected HDD.
IMPORTANT:
Note the following for the rebuild:
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.
