Hi Gerold,
the tivoli.tsm.devices.aix5.rte contains tools for testung
changer/robotor and tapes They are called lbtest(64) and mttest(64).

Ttry to get a trial & buy Version of TSM Server and install or just
extract the tools. I think these tools are working also with non-TSM
Devices.

Also check if you could find the Atape.devices fileset for Standard IBM
Devices which should also contain the tools mentioned above.
