Control Unit Port
Forgive me if this becomes a repeat post. I got a message saying that delivery of the original has been delayed. IO see that it is not yet in the archives, so I am re-posting. One of our h/w people asked me if we are using the CUP on VM. I replied by asking him what a CUP does. He gave me the landline equivalent of a blank stare. I guess I have to pose the question to the list because I have no idea how to answer his original question. Regards, Richard Schuh

Re: Control Unit Port
I wonder if he / you are referring to port 0 (zero) on a real 3174 type control unit ??? Bubba
Re: Control Unit Port
The CUP port is a management port on a FICON Director/switch. It has virtual port address of FE on each switch. Typically the CUP device address is defined in IOCP for each switch using the switcg ID and port addres to form the devices address. Example. Switch 61 might have the CUP port device address of 61FE. In a zOS environment you can setup jobs to sample RMF data to find out switch level performance data, such as switch port status, average frame size, port throughput, etc. I don't know if the CP MONITOR can sample and report on FICON switch performance, but if it did it would use the CUP port to get these stats. Perhaps Barton or Bill B. could chime in on that point.

Re: Control Unit Port
Ficon director is the more likely meaning. He said something about reporting errors, but could not clarify whether or not he was referring to EREP.

Re: Control Unit Port
I think that Mike Rydberg hit the target. I took a quick look at the PPT presentation that August Carideo suggested at www.ohvcmg.org/download/22/http://www.ohvcmg.org/download/22/ .That must be the CUP in question. What I did see was several mentions of z/OS and none that I noticed of VM. So the question remains, is the CUP used for anything in performance monitoring and reporting in VM? I know that our h/w people do not use VM for dynamically configuring anything.
