I am wondering something similar.
We have partitioned the MSL 2024, so that 1 logical library and drive is used be Veeam, the other one should be used by the LTFS Automation.
Is there a way that we can say, Veeam should only use one library, and doesn't see the 2nd one?
I saw I can disable a tape, which might help to prevent locks even it queried the tapes, but still it sees tapes in the other libary and I am not sure what it's going to do if tapes are used up, if just the tape is disabled.
I read about registry keys to prevent locking for a longer time, but that was Version 7. So I am wondering what the way to go is.
