Question fo mainframers - how can I see the relationship between mainframe logical devices (VOLSER or Device Address) and their physical EMC devices? Can I do this from my ECC with SYMCLI commands? I see there is a MF product called EzSM (z/OS Storage Manager) which does this, but we do not have this. I am getting the run-around on this from EMC, so I thought I would ask this community.  Thanks!
