Yes.
Even 10 LPARs may share the chpids and proper CU definitions allow to
create logical "any to any" connection between LPARs.
I'm not sure about translation, we call it complete polygon.
For 3 LPARs there are 3 paths
For 4 LPARs there are 6 paths
For 5 LPARs there are 10 paths
For n LPARs there are n*(n-1)/2 paths

So the 4 paths can be shared via the three LPARs?

I can't see how to share the CTC and NON CTC Control units on a Ficon card, it (HCD)
keeps generating a message that you can't "share" CTC and NON CTC on the same
CHPID, but maybe I'm doing something wrong.
