The vfradmin cgrp destroy command deletes a consistency group. To successfully delete a consistency group, you must run this command on both the source and the target systems.
To delete a consistency group, type the following command on the source and the target systems:
# vfradmin cgrp destroy cgrp_name mntpt
where cgrp_name is the name of the consistency group you want to delete and mntpt is the mount point on the source or the target system.
