CUADD on the control unit must match the LPAR you want to talk *TO* with the CTC's on that CU. Also, the CTC devices on that CU should be defined to the OS config for the LPAR's you will talk *FROM*. I always need a pad of paper when I connect CTC's...
There's a z9/z990/z900 redbook, the z900 doc ID is SB10-7034-01, "ESCON and FICON CTC Reference". Don't know the updated book is for z990, z9, z10. It's been a while since we've had to go through this en masse, but if you send me a note offline, I can perhaps send you some HCD screen shots (easier than looking at IOCP statements, IMHO).
