how do you look at the volumes, if you see them in q libvol, that is to
bee expected, as this shows you all volumes that tsm has access in the
library regardless of there storagepool. but if you see them in your q vol
command then you might have a problem, one solution to this is to define
the LTO gen 2 volumes manually to the storage pool and not have it take
scratch volumes (chance Maximum Scratch Volumes Allowed to 0 instead of
50), if you do that you can bee 100% sure that tsm wont take generation 1
tapes to that pool.

Everything working fine but if I look at volumes I can see that I have
mixed LTO1 and LTO2 tapes. So my question is what I did wrong? Please if
somebody can answer me I would be very thankful!
Thank's in advance
