text: In this configuration, one port on each node in System A and System B is configured in 
  remote copy group 1 to establish IP partnership and support remote copy relationships. A 
  dedicated inter-site link is used for IP partnership traffic, and iSCSI host attach is disabled 
  on those ports. 
  
  The following configuration process is used: 
  
  a. Configure system IP addresses properly. As such, they can be reached over the 
  inter-site link. 
  
  b. Qualify if the partnerships must be created over IPv4 or IPv6, and then assign IP 
  addresses and open firewall ports 3260 and 3265. 
  
  c. Configure IP ports for remote copy on both the systems by using the following settings: 
  
  (cid:129) Remote copy group: 1 
  (cid:129) Host: No 
  (cid:129) Assign IP address 
  
  d. Check that the maximum transmission unit (MTU) levels across the network meet the 
  requirements as set (default MTU is 1500 on Storwize V7000). 
  
  e. Establish IP partnerships from both of the systems. 
  
  f. After the partnerships are in the Fully_Configured state, you can create the remote 
  copy relationships. 
  
  (cid:2) Figure 11-107 on page 567 is an example deployment for the configuration that is shown
