Reinstalling the operating system using a
DVD
If you are reinstalling the NAS operating system onto new OS drives, you need to partition the new drives. This section
describes both how to repartition the new OS drives and how to reinstall the NAS operating system.
CAUTION: Back up the internal disk drives on your system before reinstalling or upgrading the NAS Operating
System. The DVD reinstall process formats or deletes the OS disks (virtual disk 0) resulting in loss of any data
or installed applications. The DVD reinstall process does not install RASR USB Recovery application.
The standard RAID configuration for the NX440 system is:
● OS-only - RAID 5
Refer to your configuration as-shipped from Dell for details about your specific RAID configuration.
Topics:
• Recovering an OS partition
• Deploying the OS using Dell Lifecycle Controller
