I do all of my IOGEN work from z/OS so my answer is partly base on z/OS HCD.
I defined two control units on the one channel. The first control unit had 8
devices and the second has another 8 devices.
Control Unit List Row 1 of 2
Select one or more control units, then press Enter. To add, use F11.
Processor ID . . : SYSC CSS ID . : 0 Channel path ID : 0A

_ E020 OSA 1 1 __________ OSAE-3 GbE SX QDIO SYSC P1 VSWCH

In the SYSTEM CONFIG my define statement looks like this.
DEFINE VSWITCH ADCVS01 ETHERNET RDEV E020.P01 E050.P01
I hope this helps..

Subject: z10, z/VM 5.4 and OSA Express 3
We have a new Z10 with 2 four port OSA Express 3 cards and 1 two port
OSA Express cards.
I am a little confused about the IOCP for these devices.
I am reading the IOCP manual and I am a little confused about having two
ports on a card.
Would I define one CNTLUNIT and one IODEVICE for each pair of ports? If
so, would the address.Pnn come into play with Pnn being 00 or 01 for the
port number? I am referring to the DEFINE VSWITCH command.
Continuing on, if the above is true, could I put 64 addresses on a
single IODEVICE statement and the use the Pnn format of the DEFINE
VSWITCH RDEV statement to control the addresses I use on each of the two
ports?
Example:
RDEV E000.P00 and RDEV E010.P01
I hope my question makes sense.
Regards,

It is fun to do the impossible.
