A problem was discovered in that Cisco “show zones” command is giving results such as:

zone name z23_test44 vsan 300
  fcalias name testhost vsan 300
    pwwn 10:00:00:00:c9:12:34:56 [realalias]

This confused the Show Zone parser (Revision 657 – Cisco Show Zone), plus it was ambiguous which name (“testhost” or “real alias”) should be used.

This was resolved in ShowZoneParser to use “realhost” silently; a test case was added to this project to confirm the problem is resolved going forward.
