Abstract
An improved and more efficient mapping scheme between a fiber channel (FC) interface and small computer system interface (SCSI) for multiple initiator support. In accordance with the method of the present invention an alternate mapping path is provided for processing commands from a FC host to a SCSI target while a single command is being processed therebetween through the normal mapping path. The alternate mapping path may be provided by designating another command pin(s) on the SCSI chip in the gateway or bridge box as an additional mapping address(es) or may be provided by using and coupling additional port(s) on each of the targets having multiple ports wherein the additional port(s) is/are associated with an additional mapping address(es).
