Hi Simon,

I have two different tape libraries at two different locations with multiple
media servers and all pointed to the same master server. I have also one
library with LTO2 and LTO3 tape drives in  mix and I have no any issues with
the config. Let me know what is exactly not working for you?

Thank you,
Boris
