270 Virtual Disks
concatenated virtual disks on these controllers, see Number of Physical Disks per
Virtual Disk
and Exceptions to One Physical Disk Limitation for Concatenated Virtual
Disks on CERC SATA1.5/6ch and CERC SATA1.5/2s Controllers .
NOTE: On the CERC SATA1.5/6ch controllers, this operation is not supported when
using a dynamic virtual disk or for a RAID 1 virtual disk that is in a Failed
Redundancy state.
NOTE: On Linux, a Split Mirror cannot be performed on a mounted virtual disk. For
this reason, a Split Mirror cannot be performed on the boot drive.
To Split a Mirror:
Click Split Mirror. To exit without splitting the mirror, click Go Back To
Virtual Disk Page.
CAUTION: Your virtual disk is longer redundant after performing a Split Mirror
operation.
To locate this task in Storage Management:
1 Expand the Storage tree object to display the controller objects.
2 Expand a controller object.
3 Select the Virtual Disks object.
4 Select Split Mirror from the Available Tasks drop-down menu.
5 Click Execute.

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, non-redundant concatenated virtual disk. Unmirroring
a RAID 10 virtual disk results in a single, non-redundant RAID 0 (striped)
virtual disk. Data is not lost during this operation.
NOTE: The Unmirror task is not supported on the CERC SATA1.5/2s controller.
