Unmirror
Does my controller support this feature? See Supported Features.
Use the Unmirror task to separate mirrored data and restore one half of the mirror to free space.
Unmirroring a RAID 1 or RAID 1-concatenated virtual disk results in a single, nonredundant concatenated
virtual disk. Unmirroring a RAID 10 virtual disk results in a single, nonredundant RAID 0 (striped) virtual
disk. Data is not lost during this operation.
NOTE: On systems running Linux operating systems, an Unmirror cannot be performed on a
mounted virtual disk.
To Unmirror
Click Unmirror. To exit without unmirroring, click Go Back To Virtual Disk Page.
CAUTION: Your virtual disk is longer redundant.
To Locate Unmirror In Storage Management
1. In the Server Administrator window, under the system tree, expand Storage to display the controller
objects.
2. Expand a controller object.
3. Select the Virtual Disks object.
