 There are several CLI usability features that I routinely find users are not aware of, so I thought I would share some of them here:

 Here we talk about SVC FC port virtualization, host with NPIV is supported for a long time.
+=== Change from Not virtualized to Transitional ===
 Enabling NPIV target port functionality on a new cluster
 After creating the cluster, but before starting to add hosts, issue
-  chiogrp fctargetportmode transitional <IO group>
+<cli>
+  chiogrp -fctargetportmode transitional <IO group>
+</cli>
 on each populated I/O group.
-Once that is done, issue
-  chiogrp fctargetportmode enabled <IO group>
+=== Update the zoning for ports connected to hosts ===
+    Ensure that the hosts are using the NPIV ports for host I/O. To verify that you are logged in to these hosts with these NPIV ports, enter the following command
+<cli>
+lsfabric -host host_id_or_name
+</cli>
+Wait a minimum of 15 minutes before you move from transitional to enabled state.
+=== Change from Transitional to NPIV ===
+To change the NPIV setting to enabled, enter the following command:
+<cli>
+chiogrp -fctargetportmode enabled
+</cli>
 on each populated I/O group.
 If using WWPN based zoning, issue the command to view the set of FC ports.
+<cli>
   lstargetportfc
+</cli>
 All ports that display virtualized=yes need to be zoned into hosts as described above.
