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:
1 Replace the failed hard drives.
2 Create a RAID 5 disk group across all hard drives of the DX Cluster
Services Node.
3 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 () 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
