I would delete the drive and library defintions, and redefine them to TSM.
If they define ok, them checkin your scratch tapes, followed by the
private tapes.

If you cannot redefine the library and drives, then I would look at
upgrading atape and atldd, and removing the devices from the ODM, and
running cfgmgr.
