Reinstalling the Operating System
NOTICE:
Using the Reinstallation CD deletes all data on the operating system drive. However, it does not delete any
data on the data drives.
1. Insert the first Reinstallation CD into the CD drive.
2. Shut down the NAS system.
3. If one or both existing operating system disk drives are operational, go to step 4.
4. Turn on the NAS system.
The Reinstallation CD automatically starts the reinstallation process if the first logical volume configured on the RAID
controller is a drive that is part of a two-drive, RAID 1 group.
NOTE:
If a keyboard, monitor, and mouse are connected to the NAS system, you may receive messages during
the reinstallation that state the CD does not contain the correct file. Disregard these messages and continue with
the installation as documented in this procedure.
5. When the CD ejects, insert the second Reinstallation CD.
6. When the second CD ejects, insert the third Reinstallation CD.
The system will reboot once while the CD is inserted.
NOTE:
When the third CD ejects, the reinstallation is still in progress. The system reboots several times during
the reinstallation.
It takes approximately 30 minutes for the reinstallation to complete.
7. Check support.dell.com for the latest software and driver updates and apply any necessary updates to the NAS
system.
8. Use a client system's Web browser to connect to the NAS system.
