text: As shown in Figure 11-104, there is an eight-node System A in Site A and a four-node 
  System B in Site B. Because a maximum of two I/O groups in IP partnership is supported 
  in a system, although there are four I/O groups (eight nodes), nodes from only two I/O 
  groups are configured with remote copy port groups in System A. The remaining or all of 
  the I/O groups can be configured to be remote copy partnerships over FC. 
  
  In this configuration, two links and two I/O groups are configured with remote copy port 
  groups 1 and 2, but path selection logic is managed by an internal algorithm. Therefore, 
  this configuration depends on the pathing algorithm to decide which of the nodes actively 
  participates in IP partnership. Even if Node A5 and Node A6 are configured with remote 
  copy port groups properly, active IP partnership traffic on both of the links might be driven 
  from Node A1 and Node A2 only. 
  
  If Node A1 fails in System A, IP partnership traffic continues from Node A2 (that is, remote 
  copy port group 2). The failover also causes IP partnership traffic to continue from Node 
  A5 on which remote copy port group 1 is configured. The details of the particular IP port 
  actively participating in IP partnership process is provided in the**lsportip**output (reported 
  as used).
