At least on z/OS (not sure under z/VM) you can use switch attached FC channels for CTC's as well as other purposes (so unlike Escon you don't have to dedicate a CNC and CTC port) as FC channels use the same definition at each end.

From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of Kris Buelens Sent: Monday, July 18, 2011 1:36 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Ficon CTC's between LPAR's in same Box No HW required besides the two Ficon ports and a short cable. At the SW side: configure them in the IOCP. 2011/7/18 Crispin Hugo <crispin.h...@macro4.com<mailto:crispin.h...@macro4.com>> Is there a way I can configure CTC's between LPAR's in same physical box without going out and buying hardware? I saw somewhere that one could use share CHPID's with other devices using TYPE=FC. Does this only work if going out to Ficon switch ? I do have a Ficon express 8 card with 1 unused port, Can I do anything with that ? I do have a Ficon card with 2 currently unused ports port on it. Can this be used to join the LPAR's together by cabling 1 port to the other. All this is to create a z/VM 6.1 cse with 2 LPARs. - ------------------------------------------------------------------------ This email has been scanned for all known viruses by the MessageLabs Email Security Service and the Macro 4 internal virus protection system. . ------------------------------------------------------------------------ -- Kris Buelens, IBM Belgium, VM customer support "Email Firewall" made the following annotations. ------------------------------------------------------------------------------ Warning: All e-mail sent to this address will be received by the corporate e-mail system, and is subject to archival and review by someone other than the recipient.
