Example 8-9 shows that we added the primary host attach ports (virtual WWPNs) to 
our example host zone to allow us to change the host without disrupting its availability.
Example 8-9   Transitional host zone
zone: WINDOWS_HOST_01_IBM_ITSOV7000
                10:00:00:05:1e:0f:81:cc
                50:05:07:68:01:40:A2:88
                50:05:07:68:0C:11:00:09
                50:05:07:68:01:42:A2:88
                50:05:07:68:0C:15:00:09
7. With the transitional zoning active in your fabrics, ensure that the host is using the new 
NPIV ports for host I/O. Example 8-10 shows the before and after pathing for our host. 
Notice that the select count now increases on the new paths and has stopped on the old 
paths.
