text: As shown in Figure 11-98 on page 556, there are two systems: 
  
  – System A 
  – System B 
  
  A single remote copy port group 1 is created on Node A1 on System A and on Node B2 on 
  System B because there is only a single inter-site link to facilitate the IP partnership traffic. 
  An administrator might choose to configure the remote copy port group on Node B1 on 
  System B rather than Node B2. 
  
  At any time, only the IP addresses that are configured in remote copy port group 1 on the 
  nodes in System A and System B participate in establishing data paths between the two 
  systems after the IP partnerships are created. In this configuration, no failover ports are 
  configured on the partner node in the same I/O group. 
  
  This configuration has the following characteristics: 
  
  – Only one node in each system has a remote copy port group that is configured, and no 
  failover ports are configured. 
  
  – If the Node A1 in System A or the Node B2 in System B were to encounter a failure, the 
  IP partnership stops and enters the Not_Present state until the failed nodes recover. 
  
  – After the nodes recover, the IP ports fail back, the IP partnership recovers, and the
