We have a similar situation in which our z/OS crew prepares all the IODEFs. VM does not own the token. AFAICR, I was present when the z/OS crew made a change to write the IODEF we were using and without my doing anything, the devices were immediately added to VM.
CP and SYSTEM CONFIG are good magic. :-)

One of the z/OS systems on our processor owns the IODF TOKEN and we have
been able to add devices that have been defined on the z/OS side. Our
SYSTEM CONFIG does not have anything in it that Rick mentioned and it
has been 2-3 years now since the devices were added. I suspect that on
the VM side, after the devices were dynamically added on the z/OS lpar,
we or I did a DEF CU and a DEF DEVICE on the VM lpars.
