I had some problems with this some years ago. So, I learn something... CNC-CTC (SCTC) are for ESCON channels. The 3088 (or BCTC) are for parallel channels, a pair at each side. FICON channels can be defined both as FCTC, and can be one at each side, not necessary a pair. And with a Ficon Director, we can share a unique FICON channel, defining two or more LCUs, one for each LPAR. There are a document about this somewhere into the IBM world. Regards, Clovis

I think that with FICON you also need a CNC and CTC device to couple.
The CNC type chpid definition tells the channel to play control unit
too. But I'm willing to learn...
Lets have some beers and I will tell you stories about real 3088
devices ;-)
