Hmm, okay, well the problem here is you have one library with two different drive types and specific volumes for each. When you request a volume to be mounted, RMS does not know the difference in drives when they are all in one library. Perhaps you previously had an exit that differentiated the volumes and drives to help out RMS? Best Regards, Les Geer IBM z/VM and Linux Development
