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.
