Also, if the FICON CHPID used for the FCTC goes to a FICON Switch/Director, you can create a FCTC using only a single CHPID to connect multiple LPARs on the same CEC together. The CHPID will act as both the sender and receiver with the FCTC frames going to the switch and back on the same path.

Use the Shimon doc to design all the conections. With FICON, no need to define Chpids as CNC/CTC, all must be FC. And the Control Units and IODEVICE can be FCTC. If someone will give me the updates, I’ll reformat the paper and include another section for FICON CTCs.
