A Fibre Channel to SCSI Addressing method and system is provided. The system associates with a Fibre Channel and a SCSI bus. The system further maintains a Fibre Channel to SCSI routing table (90) and a SCSI to Fibre Channel routing table (92). The system receives a cross bus transfer of data that originates on either the Fibre Channel or the SCSI bus, respectively, and wherein the cross bus transfer is intended for a target on the SCSI bus or Fibre Channel, respectively. The apparatus translates addressing information contained in the cross bus transfer by referencing either the Fibre Channel to SCSI routing table 90 or the SCSI to Fibre Channel routing table 92.
