You need to use the information/instructions from your changer vendor and define your cleaning tape slot(s). I personally never use the backup software to manage the need for cleaning tape drives. As this sounds like a new set up, why are you trying to clean your tape drive? Is it used and unknown equipment? These are rhetorical questions - no reply necessary. LTO-5 technology rarely ever needs to be cleaned - and I mean rarely. Old carbon tapes were a different issue and required regular cleaning. I must have 30 cleaning tapes on hand. Maybe one was used once or twice with 7 drives and many TB of data. Also, your environment where the changer lives is a factor on frequency. If it is a non-computer room environment, then perhaps the need is a little more often. The tape drive should inform the changer that it needs cleaning and the changer should handle the request. I have seen this with Dell, Quantum, and SpectraLogic changers - small, medium, and large changers.
