Outlining RAID functions

Redundant Array of Independent Disks (RAID) is a technology that can

combine two or more drives for fault tolerance and continuous service.

The CallPilot RAID controller is a PCI RAID SCSI card that provides

high-performance disk mirroring with RAID Level 1.

With Level 1 mirroring, two equal-capacity disk drives mirror one

another. One disk drive serves as the backup copy of the other disk drive.

If one disk drive fails, the other continues to run.

RAID configuring and splitting

Working with RAID involves the following:

verifying the RAID firmware version

upgrading or downgrading the RAID firmware

configuring RAID using the LSI320-1 controller and the Ctrl+M

menu at server bootup

ensuring that your system is working and the RAID hardware is

properly configured

performing RAID splitting

synchronizing RAID after installing CallPilot software upgrades

(PEPs)

Resynchronizing RAID if the installation is successful

Resynchronizing RAID if the installation is not successful
