4-46 Configuring Your Server
Configuration by Internal RAID Controller (2.5-inch Disk Model)
This section describes how to set the internal hard disk drives as a RAID System using the Internal RAID Controller of the
2.5-inch disk model.
Rebuild
If a HDD is defective, the rebuild feature can recover the data of the defective 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 the Universal RAID Utility, the management utility of the Internal RAID
Controller . Select a HDD and start the rebuild manually.
For the detailled operation, refer to the "Universal RAID Utility
Ver2.0 User's Guide" in ExpressBuilder DVD that comes with
the server.
Auto Rebuild
The Internal RAID Controller can automatically start the rebuild without using any utility such as Universal RAID Utility.
The auto rebuild includes two modes 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 defective.
„
Hot-swap rebuild
Automatic rebuild by hot-swapping defective HDD.
IMPORTANT: Note the following for the rebuild:
„
The HDD used for rebuild should have the same capacity, rotation speed, and standard as the
defective HDD.
„
During rebuild, the processing rate is decreased because of the high 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 between the removal of the defective HDD and the installation of a substitute
HDD should be at least 60 sec.
„
If the hot-swap rebuild does not operate, perform the manual rebuild.
