So it seems that the adapter itself knows that it is attached to a switch. Thus from the AIX server side it seems ok. I assume that you have the latest adapter microcode plus AIX driver filesets installed. If you don't - update those first. What you could try then is:
firstly: have the SAN admin switch the port in question off and then on again. Check.
Secondly: if the WWN does not want to register with the switch: delete the fibre channel adapter (from slot to latest device) from the server and re-install.
# lsdev -l fcs0 -F parent
will return a slot e.g. pci03
# rmdev -dl pci03 -R
[in case of DS4K HW you might use rdac and then you need to delete dar and dac devices, too]
After all fcs, fcsi, fcsnet etc. devices are gone run
# cfgmgr
Then test again.
