I'm new to OSAs (been using CLAW devices) and after reading VSWITCH information for z/VM 4.4, 5.1 and 5.2 have probably made this more difficult that it really is.
I've installed z/VM 5.2 and successfully run the IPWIZARD (specified QDIO, ETHERNET, NONE and 1500). If I want to use VSWITCH for z/VM TCPIP what should PROFILE TCPIP and SYSTEM DCTPARMS look like? It seems something should be done with DEVICE, LINK and START in PROFILE TCPIP and with attach in SYSTEM DCTPARMS. I assume TCPIP will need a NICDEF directory control statement as well. I believe I'm clear on the controller's PROFILE TCPIP (VSWITCH CONTROLLER ON) and its aspects of SYSTEM DCTPARMS (:nick.DTCVSW1 :type.server :class.stack). Thank you.

To use VIPA requires that you have two adapters connected to VM TCP/IP. With a VSWITCH, who needs it? If you have multiple OSAs assigned to the VSWITCH, you have built-in failover.
