text: As shown in Figure 11-102, remote copy port groups 1 and 2 are configured on the nodes 
  in System A and System B because two inter-site links are available. In this configuration, 
  the failover ports are not configured on partner nodes in the I/O group. Instead, the ports 
  are maintained in different remote copy port groups on both of the nodes. They remain 
  active and participate in IP partnership by using both of the links. 
  
  However, if either of the nodes in the I/O group fail (that is, if Node A1 on System A fails), 
  the IP partnership continues only from the available IP port that is configured in remote 
  copy port group 2. Therefore, the effective bandwidth of the two links is reduced to 50% 
  because only the bandwidth of a single link is available until the failure is resolved. 
  
  This configuration has the following characteristics: 
  
  – Two inter-site links and two remote copy port groups are configured. 
  
  – Each node has only one IP port in remote copy port group 1 or 2. 
  
  – Both the IP ports in the two remote copy port groups participate simultaneously in IP 
  partnerships. Therefore, both of the links are used. 
  
  – During node failure or link failure, the IP partnership traffic continues from the other
