Addressing Methods and
Table Structures
Fibre Channel and SCSI systems use different methods of addressing devices. The
router has a method of translating device IDs so each SCSI device is mapped to
the appropriate Fibre Channel LUN. The SCSI buses establish the bus connections
between devices. Targets on a SCSI bus may internally address LUNs. The
addressing of a specific SCSI device is represented by the BUS:TARGET:LUN
triplet.
When a Fibre Channel Initiator initializes on a loop, the host must first determine
what devices exist on the loop. Device discovery is performed and an FCP target
device list is built. Each device is queried for FCP LUNs (the LUNs are the actual
devices that the operating system will address.) The addressing used is the SCC
Logical Unit Addressing and Peripheral Device Addressing method, shown in
through
. First level addressing is supported, so only the first
two bits of the 8 bit FCP LUN are used.
