We stumbled across the answer and wanted to document it here in case someone
else runs into this problem in the future. The physical port on the z9 had
to be added to the zone definition on the switches before we could get it to
log into the remote storage through the remote switch. The z9 WWPN did not
need to be in the zone definition if only the local switch was used.

We're running into a configuration issue trying to get NPIV FCP
connections to work through a switched fabric distributed across two
locations. At our primary location, the z9 FCP is connected into Switch #1,
a McData 3232 switch. We have EMC DMX3 storage connected to Switch #1 as
well and are able to get the NPIV id logged onto the fabric, provisioned,
and connecting to the storage without a problem. We have Linux guests
booting off of the SAN and are not using 3390 disk for them. We setup the
switch binding and added the WWPN of the z9 port as a detached node on
switch #1 to get this to work. That's the good news.
The problem we are having is getting the NPIV id logged into our backup
location DMX3 which is connected to Switch #2, another McData 3232 switch
ISL'd to Switch #1. We thought we had a setting incorrect on the switches
so that the traffic is not making it all the way to the second DMX3, however
when we use the SCSIDISC utility under VM against the device which
corresponds to the NPIV id, it actually detects the storage port on the DMX3
but the DMX3 shows that we are not logged into the storage port with the
NPIV. We've tried multiple settings on the switches to get this connected,
but without any success. We have the NPIV and Switch Binding features
active on both McData 3232 switches even though I believe we only need NPIV
on the switch that the z9 port physically connects to.
Has anyone else done this and do you have suggestions as to settings we
should look at?
