Slot number does not appear in Media List GUI

[rsamora]

I use Aptare to report on my NBU setup.  I am trying to run a report that will send me an email every morning listing the number of Scratch tapes available.  I have a report configured to show me all Scratch tapes that do not have null listed in the media slot column.  I was showing hundreds of available tapes every morning even though I could see there were only 80 or 90 in the library.  It's then that I realized that all of the media that appear in the GUI have a "-" listed in the slot number column.  Has anyone ever experienced this; where no slot numbers are listed in the GUI?  I have an open ticket but thought I'd ask the gang.  The slot number is set to "Show" and not "Hide" so that's not the problem.  Any ideas?

Thanks,
Randy

According to the Veritas NetBackup Device Configuration Guide:

Unlike other robot types, Netbackup does not track slot locations for the media in ACS robots. The Automated Cartridge System Library Software tracks slot locations and reports them to NetBackup.

I have a StorageTek ACSLS library.  It's not the answer I wanted but it is the answer.
