5. Ensure that the primary host attach WWPNs (virtual WWPNs) now allow host traffic, as 
shown in bold in Example 8-7.

6. Add the primary host attach ports (virtual WWPNs) to your host zones but do not 
remove the Storwize V7000 WWPNs that is in the zones. Example 8-8 shows a host zone 
to the Primary Port WWPNs of the Storwize V7000 nodes.
Example 8-8   Legacy 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
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.
