Reconfiguring a Volume
NOTICE:
When you reconfigure a data volume, all data on the existing volume is deleted. Therefore, it is important to
back up your data before reconfiguring a volume.
1. Manually remove all shares and persistent images before reconfiguring the volume.
NOTE:
If the volume is in use or contains shares or persistent images, you cannot reconfigure the volume. The
message Use Array Manager is displayed. The administrator can use Array Manager to force deletion of the
volume. See "
Using the Array Manager to Manage Your Disks and Volumes
" in "Advanced Disk and Volume
Management."
2. If a message is displayed during the deletion process indicating that the deletion cannot be completed, use Array
Manager to perform this task.
See "
Using the Array Manager to Manage Your Disks and Volumes
" in "Advanced Disk and Volume Management."

4. Click Disks.
5. Click Volumes.
6. In the Volumes column, select the volume whose properties you want to view by clicking the adjacent radio button.

If Repair appears instead of Reconfigure, your volume is damaged and needs to be repaired. See "
8. Select the New Layout, which is either Single RAID-5 or Single RAID-0.
NOTE:
RAID-0 volumes are not fault-tolerant and do not provide data protection if a drive fails.
9. Click OK to delete and reconfigure the volume.
NOTE:
If the volume is in use—for example, if the volume is open in a browser window, the volume contains
shares or snapshots, or another application is using the volume—a message displays indicating that the
operation has failed and you need to use Array Manager. See "
Advanced Disk and Volume Management
" for more
information.
Repairing a Volume
The operating system is loaded on a fault-tolerant RAID-1 mirrored volume, and data drives are originally configured as
RAID-5 volumes. If an operating system drive or a data drive fails, use the NAS Manager to repair the volume and restore its
fault tolerance.
NOTE:
RAID 0 volumes are not fault-tolerant and cannot be repaired.
1. Shut down the NAS system.
