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.
