Managing NAS System Volumes
Managing Software-RAID NAS System Volumes
A volume is an allocation of usable space on one or more physical disks. The NAS Manager allows you to reconfigure, repair, or view the properties of a volume
in a software-RAID NAS system.
The following sections provide instructions on how to reconfigure and repair software-RAID NAS system volumes.
Reconfiguring a Software-RAID NAS System Volume
1. Prior to reconfiguring the volume, manually remove all shares and persistent images.
2. If during the deletion, the system messages that it cannot complete the deletion, then use Array Manager.
See " Using Array Manager to Manage Your Disks and Volumes " in the "Advanced Disk and Volume Management" section of this guide.
3. Log in to the NAS Manager.
See " Logging in to the NAS Manager " in this section of the guide.
4. Click Disks.
5. Click Volumes.
6. In the Volumes column, select the volume that is to be reconfigured.
7. On the Tasks list, click Reconfigure.
8. Select the New Layout, which is either Single RAID-5 or Single RAID-0.
9. Click OK to delete and reconfigure the volume.
NOTICE: This section provides instructions on how to use the NAS Manager to administer software-RAID and hardware-RAID NAS system volumes. For
instructions on how to determine if you have a software-RAID or a hardware-RAID NAS system, see " Determining if a NAS System Uses Software RAID or
Hardware RAID " in this section of the guide. Ensure that you use the appropriate section for your NAS system's RAID configuration.
NOTE: You can also create volumes in Array Manager. See " Creating a Dynamic Volume " in the "Advanced Disk and Volume Management" section of this
guide.
NOTICE: Do not perform the volume reconfiguration and repair procedures in this section on a hardware-RAID NAS system. See " Managing Hardware-
RAID NAS System Volumes " in this section of the guide to configure those volumes. For instructions on how to determine if you have a software-RAID or
a hardware-RAID NAS system, see " Determining if a NAS System Uses Software RAID or Hardware RAID " in this section of the guide.
NOTE: If the volume is in use—for example, the volume is open in a browser window, the volume contains shares or snapshots, or another
application is using the volume—a message displays stating that the operation has failed and that you need to use Array Manager. Ensure that
you delete all shares and persistent images on that volume. The administrator can use Array Manager to force the deletion of the volume. See the
"
Advanced Disk and Volume Management " section of this guide for more information.
NOTICE: Regardless of how many data drives exist, the reconfiguration procedure deletes all data and creates a single volume of the desired RAID
group.
NOTE: Reconfigure appears only if all of the disks in the NAS system are functioning properly. If Reconfigure does not appear, one or more of
your volumes is damaged and requires repair. See " Repairing a Software-RAID NAS System Volume " in this section of the guide.
NOTE: RAID 0 volumes are not fault-tolerant and do not provide data protection if a drive fails.
