The 

Configuration\Fibre Channel

 menu is used to configure the Fibre 

Channel Option to the host. 

This value represents the Id Mode, which must be configured for either “Soft” or 
“Fixed” addressing. Using “Soft” addressing, the Fibre Channel Option connects to an 
arbitrated loop using the first available AL_PA, scanning from the highest valid ad-
dress to the lowest. Using “Fixed” addressing, the user selects a specific arbitrated 
loop address (AL_PA) to connect with. If the selected address is not available, the Fi-
bre Channel Option will connect with the first available address it finds 

The “Loop Id” entry is displayed. 

The Loop Id is automatically assigned by the Fibre Channel loop 
insertion protocol. 

During the Fibre Channel Arbitrated Loop (FC-AL) initialization process, a unique 
Arbitrated Loop Physical Address (AL_PA) value is assigned to each port on the loop. 
Not all of the 256 hex values are allowed as AL_PA values per FC-AL. The Loop Id 
value is used to represent the 126 addresses that the Fibre Channel Option can use. 

Table 7-1 shows how a Loop Id value maps to an AL_PA. If “SOFT” is requested for 
the “Loop Id”, the Fibre Channel Option will attempt to obtain an available Loop Id, 
in the following order: 0, 1, 2, etc.
