Features of On-board RAID (MegaRAID ROMB)

This section describes the features of the on-board RAID (MegaRAID ROMB).
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 or RAID5 level.
Manual Rebuild
The manual rebuild can be performed by using MegaRAID Storage Manager (called MSM
hereafter), the management utility of the on-board RAID (MegaRAID ROMB). Select a HDD and
start the rebuild manually.
For the detailed operation, refer to the "MegaRAID Storage Manager User's Guide" in NEC
EXPRESSBUILDER CD-ROM that comes with the server.
Auto Rebuild
The on-board RAID (MegaRAID ROMB) can automatically start the rebuild without use of any
utility such as MSM.
The auto rebuild includes two types as follows:
Standby rebuild
Automatic rebuild by using hot-spare disks. In the configuration including hot-spare disks,
the rebuild is performed automatically if a HDD assigned to a virtual disk is defected.
