The following scenario:
3 CPCs connected FICON switch (12 chpids per CPC), the switch is
connected to another switch on remote site (only 6 FICON ports), several
tape drive CUs (12 chpids total) connected to the remote switch.
Drawing:
3CPC--SWCH1-----SWCH2--TAPE
Number of links between switches cannot be increased. I need to access
whole 12 drives from every CPC.
In the times of ESCON directors it was simply impossible , since one of
the "hops" had to be static. AFAIK in FICON world both switches can be
dynamic.
Can I put those 36 paths (12 from CU to each of 3 CPCs) to 6 links
between the sites ? Im' aware I of bandwith reduction possibility.
