Victor, yes, you can do that. the rmm CATSYNCH function does just that - retrieves all tape data sets from the catalogs and compares the results with the data sets known in its own CDS.
You need to retrieve generation data sets as well as non-vsam, request at least the devtype and volser. Check the devtyp includes the tape bit (see ucb device type for details), and ignore hsm migrated data sets (because they have a devtyp that can look like tape).
