text: **Note:**Consider the following points: 
  
  (cid:2) You can verify that you are logged in to the NPIV ports by entering the**lsfabric**
  
  **-host host_id_or_name**command. If I/O activity is occurring, each host has at least 
  one line in the command output that corresponds to a host port and shows active in 
  the activity field: 
  
  – Hosts where no I/O has occurred in the past 5 minutes show inactive for any 
  login. 
  
  – Hosts that do not adhere to preferred paths might still be processing I/O to 
  primary ports. 
  
  (cid:2) Depending on the host operating system, rescanning of for storage might be 
  
  required on some hosts to recognize more paths that are now provided by using 
  primary host attach ports (virtual WWPNs). 
  
  8. After all hosts are rezoned and the pathing validated, change the system NPIV to enabled 
  mode by entering the command that is shown in Example 8-11.

  Now NPIV is enabled on the Storwize V7000 system, and you confirmed the hosts are using 
  the virtualized WWPNs for I/O. To complete the NPIV implementation, the host zones can be 
  amended to remove the old primary attach port WWPNs.
