To add a system to a multisystem node, update the RACF® parameter libraries on all nodes to add the TARGET commands needed to add the new member system. On each system, enter the same commands from the console. (Instead of entering the commands from the console, you can create a RACF parameter library member containing the new TARGET commands, and issue a SET INCLUDE command from the console on each system.)

If the system being added to the multisystem node is not new to the network (for example, if you are joining an existing single-system node to a multisystem node), you must also delete the existing TARGET information for the system you are adding. Update the RACF parameter libraries on all nodes to remove the original TARGET commands for the single-system node. Then enter TARGET DELETE commands from the console to undo the original TARGET commands.
