Crispin, Take a look at the following redbook. This can be done with Hipersockets, an internal method of communicating between LPARS in the same box. Therefore, no need to wire any cards. Regards, Dave http://www.redbooks.ibm.com/redbooks/pdfs/sg246816.pdf

The answer is YES to all the four questions. Is there a way I can configure CTC's between LPAR's in same physical box without going out and buying hardware? 1- Yes, see reply 4 or if you already have a switch, see 2 and 3. 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 ? 2-Yes, it needs a Ficon Director. In the same CHPID you can define simultaneously LCUs type FCTC, Tape or Dasds. I do have a Ficon express 8 card with 1 unused port, Can I do anything with that ? 3- Yes, but needs a switch to "close the loop". Define the CHPID as shared to the 2 lpars, and LCU/IODEVICE type FCTC. 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. 4- Yes, define several LCUs type FCTC. The parameter CUADD must match the destination LPARid. Replied by (mine, not so good) memory, see the IOCP manuals for details... ;-) ______________________________________________ Clovis From: Crispin Hugo <crispin.h...@macro4.com> To: IBMVM@LISTSERV.UARK.EDU Date: 18/07/2011 17:29 Subject: Ficon CTC's between LPAR's in same Box Sent by: The IBM z/VM Operating System <IBMVM@LISTSERV.UARK.EDU> ________________________________ Is there a way I can configure CTC's between LPAR's in same physical box without going out and buying hardware?

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. . ------------------------------------------------------------------------ ******************************************************************************** This e-mail and any files transmitted with it, are confidential to National Grid and are intended solely for the use of the individual or entity to whom they are addressed.
