For a consistency group in the ConsistentSynchronized  state, this command causes a Consistency Freeze. 

## 10.9.13 Deleting Metro Mirror/Global Mirror relationship 

Use the rmrcrelationship  command to delete the relationship. Deleting a relationship delete only the logical relationship between the two volumes. 

If the relationship is disconnected at the time that the command is issued, the relationship is deleted only on the system on which the command is being run. When the systems reconnect, the relationship is automatically deleted on the other system. Alternatively, if the systems are disconnected and you still want to remove the relationship on both systems, you can issue the rmrcrelationship  command independently on both systems. 

A relationship cannot be deleted if it is part of a consistency group. You must first remove the relationship from the consistency group. If you delete an inconsistent relationship, the auxiliary volume becomes accessible even though it is still inconsistent. This situation is the one case in which MM/GM does not inhibit access to inconsistent data. 

## 10.9.14 Deleting Metro Mirror/Global Mirror consistency group 

Use the rmrcconsistgrp  command to delete an MM/GM consistency group. You can issue this command for any consistency group. 

If the consistency group is disconnected at the time that the command is issued, the consistency group is deleted only on the system on which the command is being run. When the systems reconnect, the consistency group is automatically deleted on the other system. 

Alternatively, if the systems are disconnected and you still want to remove the consistency group on both systems, you can issue the rmrcconsistgrp  command separately on both of the systems. 

If the consistency group is not empty, the relationships within it are removed from the consistency group before the group is deleted. These relationships then become stand-alone relationships. The state of these relationships is not changed by the action of removing them from the consistency group. 

## 10.9.15 Reversing Metro Mirror/Global Mirror relationship 

Use the switchrcrelationship  command to reverse the roles of the master volume and the auxiliary volume when a stand-alone relationship is in a consistent state. When the command is issued, the wanted master must be specified. 

## 10.9.16 Reversing Metro Mirror/Global Mirror consistency group 

Use the switchrcconsistgrp  command to reverse the roles of the master volume and the auxiliary volume when a consistency group is in a consistent state. This change is applied to all of the relationships in the consistency group. When the command is issued, the wanted master must be specified. 

Important:  Remember that by reversing the roles, your current source volumes become targets, and target volumes become source volumes. Therefore, you lose write access to your current primary volumes.
