Mark, ISFC links can be ESCON CTC or FICON CTC. I don't know why Hipersockets aren't supported, but they're not. If you really want to share SFS filepools between LPAR's on the same CEC without using a CTC, you could set up IPGATE using TCP/IP over a Hipersocket. Note that IPGATE is not officially supported. It's a sample program.
Dennis "Decision" is not a verb. From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Mark Pace Sent: Thursday, September 30, 2010 08:24 To: [email protected] Subject: [IBMVM] z/VM ISFC links >From the connectivity manual - VM domain controllers must use channel-to-channel (CTC) links to be attached to other VM domain controllers in the CS collection. The VM domain controllers may be running ISFC or VM PWSCF to participate in the CS collection. Are these links ESCON CTC or FICON CTC - or does it matter? Why doesn't ISFC take advantage of Hipersockets? You've got this high speed "network" built in to System Z, seems odd that I have to use "old fashioned" hardware connections. -- Mark D Pace Senior Systems Engineer Mainline Information Systems
