    You have both hcart3 and hcarr2 drives, only hcart3 STU in STU-group, and only hcart2 tapes.
    hcart2 tapes cannot be used in hcart3 STU.

    Make EVERYTHING hcart2.
    Drives, STU, media (already there). It will work.

    Only change drives to hcart3 when you have LTO6 tapes and have added them as hcart3 along with hcart3 STU.

    Oh, you only showed us STU group config, not individual Storage Units ('bpstulist -L' will be better than screenshots.)

    Anyway, until you have LTO6 tapes (hcart3), forget about hcart3 drives and STU. Use everything as hcart2.

    Remember to increase the amount of drives in hcart2 STU.

OK so does your media list show HCART3 media available in the Robot? Or are all your media HCART2?

        Thanks for helping me, I've just changed my HCART3 Drives to HCART2 , but I have some policies running , and as you know changing drive types needs the services to be restarted , so I will inform you as soon as my jobs finish.

        Thanks So much for such great availability and patiency.
