Addressing, structures, and operations

Fibre Channel and SCSI systems employ different methods of addressing devices. The inclusion of a 

network storage router requires that a method of translating device IDs be implemented so that each SCSI 

device is mapped to the appropriate Fibre Channel LUN. The SCSI buses establish bus connections 

between devices. Targets on a SCSI bus may internally address logical units. 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 logical units. The logical units are the actual devices that the operating system will address. When an 

initiator addresses a logical unit, the LUN field used is consistent in form with the SCC defined fields.   All 

current Fibre Channel host bus adapter drivers are consistent with these methods. The addressing used is 

the SCC Logical Unit Addressing and Peripheral Device Addressing methods, shown in 

Table 16

 and 

Table 17

.   First level addressing is supported, so only the first 2 bytes of the 8-byte FCP LUN are used.
