40 Disaster Recovery

You can use the following methods to monitor the health of the disks:

• Hard drive LED indicators—Monitors the drive activity and reports

failures. For more information, see the system’s

Hardware Owner's Manual

at support.dell.com/manuals.

• Dell OpenManage Server Administrator—Monitors the health of the

internal disks.

• Dell Management Console—Centrally monitors the status of Dell

systems. For more information about installing and using DMC, see the

Dell Management Console User's Guide

at support.dell.com/manuals.

Reinstalling the Operating System

The operating system is preinstalled on the DX Cluster Services Node. After a

multiple disk failure of the system’s RAID group, reinstall the operating

system:

Replace the failed hard drives.

Create a RAID 5 disk group across all hard drives of the DX Cluster

Services Node.

Reinstall the operating system. For more information on replacing the hard

drive, see "Recovering From Disk Failures" on page 39.

NOTE: If the RAID group has not failed and you are reinstalling the operating

system, skip "Configuring and Managing RAID" on page 40.

Configuring and Managing RAID

The BIOS Configuration Utility (<Ctrl><R>) is a storage management

application embedded on the PERC H700 card that configures and maintains

RAID disk groups and virtual disks. The BIOS Configuration Utility is

independent of the operating system and is available during system startup.

See the Dell PowerEdge RAID Controller (PERC) H700 and H800 User's

Guide at support.dell.com/manuals for more information about the BIOS

Configuration Utility and virtual disk management.

Create a single RAID 5 group across all six internal drives. When creating the

RAID group, configure two virtual disks.

• Set virtual disk 0 to 75 GB

• Set virtual disk 1 to size of the remaining capacity
