The library was given a command to move the media from a slot, but there was no media in that slot. This is usually because something other than NetVault has moved media. When NetVault starts, it asks the library what it has, and gets a list of slots that have media in them, and barcode information. After that, there are no messages sent to NetVault if something outside of NetVault moves a tape.

If you need to move tapes from outside NetVault, you must first go to device management, right click on the library, and select "Open Door". This puts NetVault in a state where it doesn't know what is in the library. When you are finished, right click on the library and select "Door Closed". NetVault will then ask the library what it has again, and everything will work normally.
