Chapter 3 Features of Disk Array
Controller
This chapter describes the features of the disk array controller.
1. 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.
1-1. Manual Rebuild
The manual rebuild can be performed by using MegaRAID Storage Manager
MSM hereafter), the management utility of the disk array controller. Select a HDD and start
the rebuild manually.
For the detailed operation, refer to the "MegaRAID Storage Manager
NEC EXPRESSBUILDER CD-ROM that comes with the server.
1-2. Auto Rebuild
The disk array controller 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.
Hot-swap rebuild
Automatic rebuild by hot-swapping defected HDD.
