## Remember: 

The following information can be useful: 

GLYPH<SM590000> 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 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 extra paths that are now provided by using primary host attach ports (virtual WWPNs). 

8. After all hosts are rezoned and the pathing is validated, change the system NPIV to enabled  mode by entering the command that is shown in Example 8-13. 

IBM_2145:ITSO-SV1:superuser>chiogrp -fctargetportmode enabled 0 

NPIV is enabled on the IBM Spectrum Virtualize system, and you confirmed that 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. Example 8-14 shows our final zone with the host HBA and the SAN Volume Controller virtual WWPNs. 

zone: WINDOWS_HOST_01_IBM_ITSOSV1 10:00:00:05:1e:0f:81:cc 50:05:07:68:01:42:A2:88 50:05:07:68:01:12:A2:88 50:05:07:68:0C:15:00:09 50:05:07:68:0C:17:00:09 

Note:  If there are still hosts that are configured to use the physical ports on the SAN Volume Controller system, the system prevents you from changing fctargetportmode  from transitional  to enabled , and shows the following error: 

## 8.4 Hosts operations by using the GUI 

CMMVC8019E Task could interrupt IO and force flag not set. 

This section describes performing the following host operations by using the IBM Spectrum Virtualize GUI: 

GLYPH<SM590000> Creating hosts 

GLYPH<SM590000> Advanced host administration 

GLYPH<SM590000> Adding and deleting host ports
