    what is the netbackup version and os on the media server.? Are the drives shared.?

    You would need to start with the system logs on the media server to identify why the drives are marked down..

        I hope you are aware that nbu 7.6 is out of support..

        Start with the event viewer logs on the media server.. you should see some messages reported when the drive is marked down.. Apart from that robots and bptm logs can also be referred.

        Most probably there maybe a tape in the drive and the original slot from which it was picked may be currently full
