Administrator Guide

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.

Steps

1 Back up data that is stored on any internal disk drives or external storage arrays.

2 If required, connect the external USB DVD drive to your NAS system.

3 Insert your Dell Storage NAS operating system resource media into your NAS system.

4 Restart your NAS system and ensure that your NAS system boots from the resource media.

The OS prompts the user if they want to delete VD 0. This process takes around 60-90 minutes to complete. Errors encountered are

also agged on the front panel LCD of your device. To resolve issues, see the Dell Storage Network Attached Storage (NAS) Systems

Using Windows Storage Server 2016 or 2012 R2 available at Dell.com/storagemanuals.

5 After reinstalling the OS, complete the initial conguration tasks listed in the Initial conguration of your NAS system section.

Dell Rapid Appliance Self Recovery (RASR)

NOTE: To prevent data or application loss, backup the OS drives before reinstalling NAS OS.

RASR provides a method where the administrator can restore the Dell Storage NX appliance to the factory default settings from a bootable

USB recovery drive. To create the RASR USB drive, double-click the Create RASR USB Recovery Drive icon on the Windows Desktop. It

is highly recommended to create an RASR USB drive immediately after completing the NAS initial system conguration as referenced in the

Initial conguration of your NAS system section.

NOTE

: This option is only available from factory conguration and not available if the system is restored from DVD.
