Use the chcekout libvolume command to
checkout the generation 2 tapes then check them back in with status=pri,
then use the define volumes command to define them into the storage pool,
just be carefull to use the exact name that shows up in the libvolume command.
then you need to update the storage pool to max scrach to 0 make
the gen 1 tapes in the gen 2 storagepool readonly and move the data to
the same pool with move data command.

This labels with A001* are LTO1 tapes! How can I assign LTO2 tapes to a
specific StoragePoll? I have lot of Scratch volumes! If you could explain
me in a short how to do that!
Thank You in advance!

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
