Table 3-1. Features of the PERC S100 controller and PERC S300 controller

RAID Controller Feature Description

Automatic virtual disk

rebuild

Rebuilds a redundant virtual disk automatically when a

failure is detected, if a hot spare is assigned for this capability.

Background Array

Scan (BAS)

Verifies and corrects correctable media errors on mirror,

volume, or parity data for virtual disks. BAS starts

automatically after a Virtual Disk is created while in the OS.

Background virtual

disk initialization

(BGI)

The background initialization of a redundant virtual disk

creates the parity data that allows the virtual disk to maintain

its redundant data and survive a physical disk failure.

Because background initialization helps the controller to

identify and correct problems that might occur with the

redundant data at a later time, background initialization is

similar to a consistency check.

Background initialization allows a redundant virtual disk to

be used immediately. Data is lost if a physical disk fails before

the completion of a BGI.

NOTE:

Although a BGI is software-initiated at the PERC Virtual

Disk Management utility, the PERC S100 adapter/PERC S300

adapter drivers must be loaded before the BGI runs.

NOTE:

Unless mentioned otherwise, the term PERC Virtual Disk

Management utility refers to both the PERC S100 Virtual Disk

Management utility and the PERC S300 Virtual Disk

Management utility.
