I study all the fields in the distributed UCB DSECT(s) fairly often, and have not seen such an element. What would be much more useful, IMHO, is a callable system service that would return useful information, such as system IDs and device numbers on each system, about all the systems on which a given device is currently online. But that's not very likely to be generally available from IBM any time soon. And such information would always be suspect due to its possibly having changed on another system before the query ends. And at what overhead cost with all the required inter-system communication?

I don't think so. I run a DCOLLECT on all my systems then assign a column / value from the system id and print out various stats about the volume. It does assume the same UCB on all systems.
