I have an issue where my SAN nodes are logging around 300k logout/login messages per hour.
The bulk of these messages relate to a wwn starting with 21:fd:xx:xx:xx:xx:xx:xx but I cannot find this anywhere on the actual switch itself.
When running 'nsshow' from the switch CLI I can see that all responses have the same last 6 octets (ie xx:xx:xx:xx:xx:xx from above) but they begin with things tlike 20:01 20:08, etc.
This is obviously based on the Brocade portthat things are connected to.
For the life of me, I cannot find any reference to anything starting with 21:fd:..........
Ihave tried running the QLogic utility on my SAN nodes that run Win 2012 R2 but haven't been able to get that to work for some reason.
Ideally, I would like to identofy what this wwn refers to, whether it is necessary and (ultimately) how to fix and/or deactivte this from my SAN nodes.
Can someone point me in the right direction here as this is definitely having a performance impact.

I permanently disabled those ports, but I don't believe that was the issue.
My switch has a wwn of 10:00:00:05:1e:02:3c:26
All ports on the switch have a fabric port name of 21:xx:00:05:1e:02:3c:26 (from nsshow command)
The port/ww/whatever I am looking for has a wwn of 21:fd:00:05:1e:02:3c:26
This phantom wwn is attempting to login to my SAN at the rate of around 300k times per hour.
This is creating a lot of 'noise' on my SAN and affecting performance.
As a result, I am trying to figure out what this is and (if it can be done safely) disable it.
I had a feeling this may have something to do with the Name Server but have had no success in finding it.
Do you have any advice on this one?
