> HCP954I DASD rdev1 VOLID volid IS A DUPLICATE OF DASD rdev2 Nonetheless, I believe that the message begs the question: why is that an "I"-level information message rather than a "W"-level warning message?
The operator response states: "Operator Response: Verify that the volume mounted on DASD rdev1 is the one to be used by the system. If it is not, CP may perform incorrect allocation on the volume specified. Shut down the system and remove the incorrectly labeled volume that is a duplicate. This message usually occurs after a system restart when users have mounted volumes with labels identical to those of other user or CP volumes." I believe that "CP may perform incorrect allocation on the volume specified. Shut down the system and remove the incorrectly labeled volume that is a duplicate." are pretty outage-intensive warnings. If the situation could be that critical, it should be a Warning-level message. I'll open a PMR for this. Mike Walter Aon Hewitt The opinions expressed herein are mine alone, not my employer's.

But you can still wind up with the wrong volser mounted if the right device doesn't respond for some reason, as Alan has said. -- .''`.
