reinstall the operating system:
l Reinstall the operating system using a dedicated Microsoft® Windows® 2000 client system
l Reinstall the operating system using a Windows 2000 system that is on the same LAN
¡ With a DHCP server
¡ Without a DHCP server
l Use an existing Preboot Execution Environment (PXE) server
Booting From the Recovery Operating System Mirror Hard Drives
NOTE: If the repair button does not appear, then you do not have a drive the same size or larger than the failed drive, you did not have the drive
in the system when the system booted, or you were not using a RAID 5 volume. Use Dell OpenManage™ Array Manager to repair or reconfigure
your volumes. See "
Using the Array Manager to Manage Your Disks and Volumes " in "Advanced Disk and Volume Management."
NOTE: The NAS system takes approximately 5 minutes to boot completely.
NOTE: If the repair button does not appear, then you do not have a drive that the same size or larger than the failed drive, you did not have the
drive in the system when the system booted, or you were not using a RAID 5 volume. Use Array Manager to repair or reconfigure your volumes.
See "
Using the Array Manager to Manage Your Disks and Volumes " in "Advanced Disk and Volume Management."
NOTICE: The reinstallation procedure resets your NAS system to the Dell™ default settings and deletes all data on the NAS system. Before performing
this procedure, attempt to boot from the operating system image on the mirrored hard drives. See " Booting From the Recovery Operating System Mirror
Hard Drives ."
