Split Mirror
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.
NOTE:
On Linux operating systems, 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.

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.
