Problem with VTL (duplicate or Catalog) Media

hello,

when i try to duplicate/catalog backup sets from HP D2D (VTL) to a phusical tape (Robotic Library), I always get the two screen shots attached.

also some time when I try to duplicate the backup sets, I only get some data successful and other are not duplicated (the data on the D2D media is more than 1.3 TB and the duplicated data is only 20 GB !!)

I have CASO server and 3 MMS servers, all D2D libraries and Tape library are shared between them

I have D2D library for Database, Exchange and File server

I'm trying to duplicate backup set from File server library or Exchange library to a physical tape, it always stuck as the attached picture
