nothing except for this command issued from the command prompt on the cell manager
omnimlist -device "[device name]" -slot # -monitor -catalog Do not include the [ ] marks
where "[device name]" is the name of a logical device, and # is a slot number; the tape will be loaded, and the segment headers will be read. I strongly suggest that you redirect this output to a file, so, for example
omnimlist -device "LTO Drive-2" -slot 14 -monitor -device > C:\temp\tape_14_filenames.txt
In this example, the " marks were required because the logical device has a 'space' in it
