    If robtest is failing, generally speaking you have a hardware issue of some sort.

    m sx dy is just a scsi command that asks the library to move a tape from slot to drive, or drive to slot.

    If the robot doesn't do this, it's down to the library.

    It could be as simple as a tape stuck in a drive, can you move other tapes to / from other slots/ drives ?

    You could try :

    unload 2

    m d2 s3

    If that still fails, and oher drives are working, then can you manually access the robot to remove the tape.

        It seems that the tape is stuck. That is why the software eject command is not working. 

        You will need to physically inspect the robot/drive and press the eject button on the drive.

        If that does not work, or if there is an error light on the drive, you will need to contact your hardware support team.
