Had to look, but we have a 4 member MAS and all of them have the name node name. From what I can tell it shouldn't matter. I'm assuming it does not matter because they don't talk to each other.
Obviously each one has a unique member name within the MAS. Do PRD1/PRD2 have the same node name. Since SYSA/SYSB have the same node name, if PRD1 goes to connect to 'NODE SYS', I'm sure it will only connect to one, either SYSA or SYSB, because from a NJE point of view here is only one node with multiple members. If PRD1/PRD2 share node name, same thing. You may have four LPAR's, but there are only two NJE nodes.
