For a consistency group in the  ConsistentSynchronized  state, this command causes a  Consistency Freeze. 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. 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. 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. 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.  566  Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.2.1 10.9.16 Reversing Metro Mirror/Global Mirror consistency group 10.9.15 Reversing Metro Mirror/Global Mirror relationship 10.9.14 Deleting Metro Mirror/Global Mirror consistency group 10.9.13 Deleting Metro Mirror/Global Mirror relationship
