  **Remote Copy Consistency Groups**
  A Remote Copy Consistency Group can contain an arbitrary number of relationships up to the 
  maximum number of MM/GM relationships that is supported by the IBM Spectrum Virtualize 
  system. MM/GM commands can be issued to a Remote Copy Consistency Group. 
  
  Therefore, these commands can be issued simultaneously for all MM/GM relationships that 
  are defined within that consistency group, or to a single MM/GM relationship that is not part of 
  a Remote Copy Consistency Group. For example, when a**startrcconsistgrp**command is 
  issued to the Consistency Group, all of the MM/GM relationships in the consistency group are 
  started at the same time. 
  
  Figure 11-87 shows the concept of Remote Copy Consistency Groups.
