Thanks for the replies. And thanks for the TRACK commands, Mike. I use TRACK all the time but mostly for viewing consoles. TRACK shows an active I/O to a VSWITCH connected to an OSAX. I am reluctant to do a HALT on that device as I do not know if it would impact other users of the VSWITCH.
And Alan, I guess I'm glad to know we're not alone. I will look up VM64184. It is for z/VM 5.2? I saw an item on IBMLINK for a hung z/OS user and VSWITCH, but it was for z/VM 4.4. I will take a SNAPDUMP before our next IPL and open a PMR.
