Deconfiguring geographic mirroring

If you no longer want the capability to use geographic mirroring for a specific disk pool or disk pool group, you can select to Deconfigure Geographic Mirroring. If you deconfigure geographic mirroring, the system stops geographic mirroring and deletes the mirror copy of the disk pools on the nodes in the mirror copy site.

The disk pool must be offline to deconfigure geographic mirroring and the cluster resource group (CRG) must have a status of INACTIVE.
