Abstract:
A mapping scheme method between a fibre channel interface and a small computer system interface wherein a bridge box couples and bridges the fibre channel interface and the small computer system interface and wherein at least one host is coupled to the fibre channel interface and at least one target is coupled to the small computer system interface comprising the steps ofproviding a normal path and at least an alternative path through the bridge box for processing mapping commands between one of the at least one target and one of the at least one host, using the normal path of the one of the at least one target to process the commands from the one of the at least one host when the normal path is available, including: coupling one of multiple ports from the one of the at least one target to one of a number of bridge box ports of the bridge box wherein the one of a number of bridge box ports is mapped and associated to a normal address, and using the normal address to process the commands, and using the at least an alternative path of the one of the at least one target to process the commands from the one of the at least one host when the normal path is not available and the at least an alternative path is available and the commands are able to use the at least an alternative path.
