Re: OSA and VSWITCH questions
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. -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of James M Sent: Thursday, November 12, 2009 4:52 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: OSA and VSWITCH questions I don't believe so.

The VSWITCH requires 3 sequential device numbers, but there is no requirement that they being with an even address. (That was a hardware requirement of OSA-1s.) If you intend to share the OSA with other partitions, you will need additional UAs. Oh, I have not done anything with the OAT table with QDIO - or any other configuration for that matter. The OAT is managed by the adapter itself when using QDIO in response to instructions from the device drivers. OSA/SF can still be used, if desired, to look at the OAT and the adapter statistics.

OSA and VSWITCH questions
I'm also experimenting with vswitch's on a test 2nd level 5.4 system. I've immediately run into the problem of my osa not being qdio capable. q osa all showing type ose. Is there a way to fool a second level system..i.e defining a virtual qdio osa device? I suspect not so my next question revolves around redefining the io definition of the osa chpid. How disruptive is that? Can I dynamically change from non-qdio to qdio? Do I have to redo the oat table? Or does the OAT go away with qdio? I'm having trouble finding the OSA documentation on the IBM web site so that would also be helpful if you could send a link. If I had that I could probably answer my own questions but any input is very appreciated. Thanks James
Re: OSA and VSWITCH questions
If you need it just for you 2nd level, you should be able to DEFINE VSWITCH and insert the NICDEF for as many adapters as you need into the directory for the 2nd level VM.

Re: OSA and VSWITCH questions
5.4 first second level. I need the second level machines to communicate with the world so I believe my only option is to reconfig the osa from ose to osd. Seems like I need a iocp change and the corresponding changes to any first level lpar tcpip stacks. Then I should be good to go on the vswitch. The osd devices are triplets rather than twins (I think) so I'm hoping thats the major difference. But I'm having trouble researching what I need to do exactly. Any idea where I can find the doc to help switching to qdio? Thanks for the help On Thu, Nov 12, 2009 at 3:52 PM, Frank M.
