text: 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. 
  
  **11.7.15 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. 
  
  **11.7.16 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.
