Firmware on IBM LTO1 is 4561, on IBM LTO2 4770. This is the latest
firmware version STK provided us, maybe there are newer versions now
available. I will check that with STK.
I know that we really dont need ACSLS to have only TSM on the library,
even with several servers.
Discussing the "Wait for rewind failed" problems with STK, one of them
mentioned we should move to ACSLS, what means investment of money and time.
I have some vague glance of hope, some error recovery in ACSLS is better
and will stop getting these errors. ???
