So, my current IOCP has:
CNTLUNIT CUNUMBR=0100,PATH=(00),UNIT=OSA
IODEVICE ADDRESS=(0100,03),CUNUMBR=(0100),UNIT=OSA, X
UNITADD=00
IODEVICE ADDRESS=(010F),CUNUMBR=(0100),UNIT=OSAD, X
UNITADD=FE
Should I generate more OSA IODEVICE addresses, say 0103, 0104, and 0105 and use 0103
as the RDEV for the VSWITCH? What's confusing is that VSWITCH RDEV wants a REAL
device, so is it possible to generate more addresses for the real OSA?

Subject: Re: VSWITCH question
The VSWITCH OSA devices are attached to no one. CP will drive them but use
the VM TCPIP stack to initialize the devices. CP uses the *VSWITCH IUCV
service to talk with the stack. The stack will issue the necessary CCWs to
get the OSAs initialized. From that point on CP will drive the devices
itself and the stack is "out of the loop".
So the answer is: use OSA devices not currently in use.
Alan Altmark gave an extremely interesting and detailed presentation on just
this issue at today's Hillgang meeting.
