Repairing a Software-RAID NAS System Volume
If an operating system drive or a data drive fails, replace the drive, and use the NAS Manager to repair the volume to make it fault-tolerant again. However, if
more than one drive fails, you must reinstall the operating system. See "
Software-RAID NAS System Hard-Drive Failures " in the "Recovering and Restoring the
System" section of this guide.
1. Remove the failed hard drive.
2. Insert a new hard drive ordered from Dell that is the same size as or larger than the failed drive.
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. Click Repair.
7. Click OK.
Viewing Software-RAID NAS System Volume Properties
1. Log in to the NAS Manager.
See " Logging in to the NAS Manager " in this section of the guide.
2. Click Disks.
3. Click Volumes.
4. In the Volumes column, select the volume whose properties you want to view.
5. On the Tasks list, click Properties.
6. Click OK to return to the Volumes window.
Managing Hardware-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, rescan the bus, or view the properties of
a volume in a hardware-RAID NAS system.
The following sections provide instructions on how to reconfigure and view volume properties in a hardware-RAID NAS system. Information on the automatic
volume repair function is also provided.
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: This option is available only on software-RAID NAS systems. Hardware-RAID NAS systems perform this function automatically when a new
blank hard drive is inserted into the system. 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: RAID 0 volumes are not fault-tolerant and cannot be repaired.
NOTE: The repair feature does not work if you insert a hard drive that is smaller than the failed drive.
NOTE: Repair appears only if the volume is damaged and you have placed a new drive in the system. The drive must be the same size as or
larger than the failed drive.
NOTE: The process of fully rebuilding the RAID volumes may take several hours.
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.
