Fibre Channel failed not seeing redundant path

Hi I recently started noticing the following issue in my messages file

Mar 17 16:23:00 pine genunix: [ID 408114 kern.info] /scsi_vhci/ssd@g290000602200

443c6257455730303138 (ssd12) online

Mar 17 16:23:00 pine scsi: [ID 243001 kern.warning] WARNING: /pci@bd,600000/SUNW

,qlc@1/fp@0,0 (fcp1):

Mar 17 16:23:00 pineFailed to create nodes for pwwn=2b00006022004433; error=5

Mar 17 16:23:00 pine luxadm[88]: [ID 434025 user.error] ID[luxadm.create_fabric_device.2316] configuration failed for line (/devices/pci@bd,600000/SUNW,qlc@1/fp@0,0:fc::2b00006022004433) in file: /etc/cfg/fp/fabric_WWN_map. I/O error

I notice that my Port B is now missing when I do luxadm display seems I only have 1 path to my SAN I would like some assitances on how to debug this problem ? I'm not sure if its software or hardware related this system is attached to a T3+ 6960 using mpxio
