-- snip -- If the unit is being used in a sysplex then the following command issued on one system should suffice :
RO *ALL,D U,,,addr However, as Shane points out if the unit is online to a system outside the sysplex, then I cannot think of a better procedure than : (a) Gulp (b) Issue the "D U,,,addr" command on each system until found. (c) Do something to ensure that this doesn't happen again (HCD, auto-ops, configxx etc etc) -- snip -- I used to work for a client that shared tape drives between IBM and Siemens hardware. Keeping a tab on which system currently has a tape assigned is possible with a little work. Rob's (b) suggestion could include some kind of a procedure that sends the Display Unit commands via TCP/IP to the different sysplexes (or OEM systems) and then returns the results. Not trivial - just an idea. The MVS command DS QTAPE can be used to return device information - but unfortunately, the assigned information is not available.
