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.

NAME

       fp - Sun Fibre Channel port driver

DESCRIPTION

       The  fp	driver	is a Sun fibre channel nexus driver that enables fibre channel topology discovery, device discovery, fibre channel adapter
       port management and other capabilities through well-defined fibre channel adapter driver interfaces.

       The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
       vate  loop  topologies,	the  driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
       LIRP and LILP stages of loop initialization.

CONFIGURATION

       The fp driver is configured by defining	properties in the fp.conf file. The fp driver supports the following properties:

   mpxio-disable
       Solaris I/O multipathing is enabled or disabled on fibre channel devices with the  mpxio-disable  property.  Specifying	mpxio-disable="no"
       activates I/O multipathing, while mpxio-disable="yes" disables the feature.

       Solaris	I/O  multipathing  may be enabled or disabled on a per port basis. Per port settings override the global setting for the specified
       ports. The following example shows how to disable multipathing on port 0 whose parent is /pci@8,600000/SUNW,qlc@4:

       name="fp"    parent="/pci@8,600000/SUNW,qlc@4"	 port=0
       mpxio-disable="yes";

   manual_configuration_only
       Automatic configuration of SCSI devices in the fabric is enabled by default and thus allows all devices discovered in the SAN zone  to	be
       enumerated   in	the  kernel's  device tree automatically. The manual_configuration_only property may be configured  to disable the default
       behavior and force the manual configuration of the devices in the SAN. Specifying manual_configuration_only=1 disables the  automatic  con-
       figuration of devices.
