Consider referring to the Brocade Fabric OS Administration Guide, v7.4, too. There, you will find that FICON will require one of the 256-area addressing modes one or two, but not the 10-bit addressing mode zero. Note the dependencies which should be taken into account for identifying the preferred addressing mode for your environment…   I hope this will help you to find your answer?  Best regards,    Swen
I am going to migrate one ficon director from DCX to 8510B.   To avoid any mainframe iocds change, I was thought to use the portaddress --bind command to change the fcid of the ports used by storage to be exactly the same as the old DCX.  I was wondering when I perform the portaddress --bind command to change the fcid will it update the port index as well.   My understanding is that the fcid is derived from the port index in hex.
