You can use the management GUI or command-line interface (CLI) to delete a copy from a volume.
The system supports mirrored copies for both standard topologies, which consist of a single site, and for HyperSwap topologies, which consists of multiple sites. The HyperSwap topology is used for high availability and disaster recovery scenarios. If you are deleting a copy to a volume used in a single system, use the rmvdiskcopy command or the management GUI. For HyperSwap volumes, use the rmvolumecopy. In the management GUI, select Volumes, right-click the volume copy, and select Delete this Copy.
