RAID Controller Feature

Description

 

 

Automatic virtual disk

Rebuilds a redundant virtual disk automatically when a

rebuild

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

 

 

Background Array

Verifies and corrects correctable media errors on mirror,

Scan (BAS)

volume, or parity data for virtual disks. BAS starts

 

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

 

 

Background virtual

The background initialization of a redundant virtual disk

disk initialization

creates the parity data that allows the virtual disk to maintain

(BGI)

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.
