Unfortunately, there's nothing in FC, outside of wwpn (and sometimes wwnn), that you can uniquely identify a device by. Since the wwpn didn't fit in the scsi_device id, it mandated a translation to something that did. A simple sequential counter was chosen. To keep things consistent, and done in a LLDD-independent manner, the FC transport owned the assignment of the counter and the persistency (and consistency) of the mapping. -- james - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
