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.

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 adhereto preferred paths might still be processing I/O to  primary ports. GLYPH<SM590000> 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.
