I did this not too long ago and I had to do the IOCP (Dynamic I/O was
not configured but it is now). My IOCP now looks like this :
CHPID PATH=(10),TYPE=OSD,PCHID=110,PART=PROD
CHPID PATH=(11),TYPE=OSC,PCHID=111,PART=PROD
CNTLUNIT PATH=(10),UNIT=OSA,CUNUMBR=1460
IODEVICE ADDRESS=(1460,15),UNIT=OSA,CUNUMBR=1460
IODEVICE ADDRESS=(146F,1),UNIT=OSAD,UNITADD=FE,CUNUMBR=1460
The one problem I did have when I tried to bring up the new IOCP was
that it took more memory and it had to be changed before the machine
would come up. I wish I could remember exactly how I did that thru the
HMC (we have a z9) but maybe someone else can enlighten you on that.
You do have to have 3 cuu's for QDIO and they must start with an
even/odd address. The third address does not have to be sequential, at
least for VSE. That way you can use all the addresses. Hope this
helps.
Oh, I have not done anything with the OAT table with QDIO - or any other
configuration for that matter.

I don't believe so.
I'm not so concerned with that as I am with the changes needed to zvm
zos and zvse once it gets changed.
Since you seem to be also using vswitch can you tell me if you have an
OAT table?
Currently my ip addresses are defined (via osa/sf) on the osa card in
conjunction with device addresses. Those device addresses are then
attached to guests in pairs who must use the assigned ip address.
I'm trying to figure out if that is the way it works with qdio devices
or does the oat go away (i'm hoping).
Can you point me at a manual to help?
Thanks again
