If the consistency group is in an inconsistent state, any copy operation stops and does not  resume until you issue the  startrcconsistgrp  command. Write activity is no longer copied  from the master to the auxiliary volumes that belong to the relationships in the group. For a  consistency group in the  ConsistentSynchronized  state, this command causes a Consistency  Freeze. When a consistency group is in a consistent state (for example, in the  ConsistentStopped ,  ConsistentSynchronized , or  ConsistentDisconnected  state), you can use the  -access parameter with the  stoprcconsistgrp  command to enable write access to the auxiliary  volumes within that group. Use the  rmrcrelationship  command to delete the relationship that is specified. Deleting a  relationship deletes only the logical relationship between the two volumes. It does not affect  the volumes. If the relationship is disconnected at the time that the command is issued, the relationship is  deleted on only 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 of the  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. This command  deletes the specified consistency group. If the consistency group is disconnected at the time that the command is issued, the  consistency group is deleted on only 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. 574  Implementing the IBM System Storage SAN Volume Controller with IBM Spectrum Virtualize V8.2.1 11.7.15 Reversing Metro Mirror/Global Mirror relationship 11.7.13 Deleting Metro Mirror/Global Mirror relationship 11.7.14 Deleting Metro Mirror/Global Mirror consistency group
