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 logical drives in the RAID1, RID5, or RAID10 level.
1-1. Manual Rebuild
The manual rebuild can be done by using WebPAM, the management utility of the disk
array controller. Select a HDD and start the rebuild manually.
For the detailed operation, refer to the online manual "Web-based Promise Array Manager
User’s Guide" saved in the "S-ATA Array Management Software" CD-ROM coming with the
card.
1-2. Auto Rebuild
The disk array controller can automatically start the rebuild without use of any utility such
as WebPAM.
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 done automatically if a HDD assigned to a logical
drive is defected.
Hot-swap rebuild
Automatic rebuild by hot-swapping defected HDD.
