Dell PowerVault 715N (Rackmount NAS Appliance) User Manual

17. Use the NAS Manager Disk and Volume tabs to monitor the status of the rebuild.
By default, the data volume is configured as a RAID 5 volume. If you prefer RAID 0, use the NAS Manager to
reconfigure the volume to RAID 0. If you perform this operation, all data on your RAID 5 volume will be lost.
NOTE:
Rebuilding the RAID 5 volume can take several hours, depending on your system configuration. While
the rebuilding of the data volume (RAID 5) occurs, the volume is available to the user.
NOTICE:
Do not change the name of the system until the volume rebuild process is complete because changing
the name requires a reboot that destroys your data. Do not establish a Terminal Services Advanced Client session
until the RAID 5 rebuild is completed.
18. Use the Kick-Start utility to reconfigure the NAS appliance after the RAID 5 volume has finished rebuilding and the
NAS appliance is displayed in the Discovered Dell Systems List in the Kick-Start window.
Recovering RAID 5 Data After Reinstalling the Operating System
Use this process if you have reinstalled the operating system and have an existing data volume in a RAID 5 configuration.
1. From the PowerVault NAS Manager, log on to the Terminal Services Advanced Client.
2. Launch the Dell OpenManage Array Manager by clicking System Management in the Advanced Administration
Menu, and then clicking Computer Management.
3. Right-click the Mirror for the D: drive containing the recovery operating system on Disk 2 and Disk 3, and then
select Delete.
4. Right-click the C: drive, select Add Mirror, and then select Disk 2 when asked to specify a disk.
NOTE:
At this point, the C: drive (Disk 0) is Dynamic. If the Array Manager reports it as Basic, upgrade it
to Dynamic before continuing.
5. After the process finishes, right-click the C: drive, select Break Mirror, and then select Disk 2.
The system displays a Volume D: in Disk 2.
6. Right-click Volume C: (Disk 0), select Add Mirror, and then select Disk 1 when asked for a disk.
7. Right-click Volume D: (Disk 2), select Add Mirror, and then select Disk 3 when asked for a disk.
8. Right-click the Data Volume, select REPAIR, and then select Disk 0 when you are prompted to specify a disk.
This step re-establishes the RAID 5 data volume.
When this process completes, the system is back to the original Dell default configuration and can recover from hardware
and software errors.
