Unmirror

Dell OpenManage™ Server Administrator Storage Management User's Guide

Does my controller support this feature? See "Appendix: 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: The Unmirror task is not supported on the CERC SATA1.5/2s controller.
NOTE: On the PERC 3/Si, PERC 3/Di, and CERC SATA1.5/6ch controllers, doing an Unmirror on a RAID 1- concatenated virtual disk results in a concatenated virtual disk that cannot be subjected to any further modification. You cannot reconfigure or add disks to the resulting concatenated virtual disk. If you do an Unmirror on a RAID 1 virtual disk, the resulting concatenated virtual disk 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.
NOTE: This operation is not supported when using a dynamic virtual disk with a PERC 3/Si, PERC 3/Di, or CERC SATA1.5/6ch controller.
NOTE: On Linux, an Unmirror cannot be performed on a mounted virtual disk.

To Unmirror:

NOTICE: Your virtual disk will no longer be redundant.
