Hi, >> How could it connect LPARs if one end goes to DASD or TAPE?
I think it is possible only with a Ficon Director (Switch). The switch "redistribute" the connections, and allow a mixed of devices (CTC, TAPEs and DASDs) on the unique Ficon channel. And you can use a single channel (not a pair) to do CTCs between several LPARs on the same CEC. The signal goes to switch and returns by the same channel, "two-way"... ______________________________________________ Clovis From: Shimon Lebowitz <[email protected]> To: [email protected] Date: 22/12/2010 08:28 Subject: Re: ISFC connection between LPARs Sent by: The IBM z/VM Operating System <[email protected]> Really? Wouldn't a FICON channel that is being used for CTC between LPARs need to have *both* ends attached to FICON cards in the computer, the way an ESCON CTC is built? How could it connect LPARs if one end goes to DASD or TAPE? I do not yet have FICON (till next month....) but I am interested in learning!

You can share them for DASD, TAPE and FICON-CTC.

We are finally getting a z10 and I need to create a link between the two main LPARs. I don't have ESCON adapters in this box and I'd really hate to use up a couple of FICON just for a CTC connection between the 2 LPARs. Is there any other way to do this on a z10? Martha
