I found a similar problem.
When doing duplicates or second copies, the tape is shown inside the proper
media set but also inside the cleaning tape set. That prevents tape from becoming usable, again.
I checked the adamm.log and device wizard but I didn't find any abnormal order among the four SDLT devices inside the Tape library
I must say I use BEXEC 10.D, windows 2003 SP1 and a four-tape libraryMessage was edited by:
