
Does my controller support this feature? See Supported Features.
Use the Split Mirror task to separate mirrored data originally configured as a RAID 1, RAID 1-concatenated, or RAID 10 virtual disk. Splitting a RAID 1 or RAID 1-
concatenated mirror creates two concatenated non-redundant virtual disks. Splitting a RAID 10 mirror creates two RAID 0 (striped) non-redundant virtual
disks. Data is not lost during this operation.

To Split a Mirror:
Click Split Mirror. To exit without splitting the mirror, click Go Back To Virtual Disk Page.

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 Split Mirror task is not supported on the CERC SATA1.5/2s controller.
NOTE: On the CERC SATA1.5/6ch controllers, doing a Split Mirror on a RAID 1-concatenated virtual disk results in concatenated virtual disks that cannot
be subjected to any further modification. You cannot reconfigure or add disks to the resulting concatenated virtual disks. If you do a Split Mirror on a
RAID 1 virtual disk, the resulting concatenated virtual disks can be reconfigured back to a RAID 1 virtual disk. After you have reconfigured to a RAID 1
virtual disk, further reconfiguration may be possible. For information on restrictions associated with 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.
CAUTION: Your virtual disk is longer redundant after performing a Split Mirror operation.
