Instance of the card “C” numbers are same as ext_bus instances
Port – third byte of N-Port ID
(1) 42 is in decimal – convert to HEX which is 2a
(2) 2a is the AL_PA
(3) Look up 2a in AL_PA table to find loop ID = 108
Will be 0 if DFA no loop id required
Area – second byte of N-Port ID
(1) 23 is in decimal – convert to HEX which is 17
(2) Divide the 17 into two nibbles or digits, the “7” means
port 7 on switch
