text: **11.8.7 Remote copy groups**
  
  This section describes remote copy groups (or remote copy port groups) and different ways to 
  configure the links between the two remote systems. The two IBM Spectrum Virtualize 
  systems can be connected to each other over one link or, at most, two links. To address the 
  requirement to enable the systems to know about the physical links between the two sites, the 
  concept of remote copy port groups was introduced. 
  
  Remote copy port group ID is a numerical tag that is associated with an IP port of an IBM 
  Spectrum Virtualize system to indicate which physical IP link it is connected to. Multiple nodes 
  might be connected to the same physical long-distance link, and must therefore share the 
  same remote copy port group ID. 
  
  In scenarios with two physical links between the local and remote clusters, two remote copy 
  port group IDs must be used to designate which IP addresses are connected to which 
  physical link. This configuration must be done by the system administrator by using the GUI or 
  the**cfgportip**CLI command. 
  
  **Remember:**IP ports on both partners must have been configured with identical remote 
  copy port group IDs for the partnership to be established correctly. 
  
  The IBM Spectrum Virtualize system IP addresses that are connected to the same physical 
  link are designated with identical remote copy port groups. The system supports three remote 
  copy groups: 0, 1, and 2.
