A good beer says you've got a mismatch of element numbers with LUN numbers.
That would explain
1) why lbtest works fine
2) why the library will load a tape (tape load uses the LUN to locate the
device), but also why it can't read, write, or unload the tape. (These
operations use the element number.)

Element match with fiber drives is tricky. Your best bet is disable (via upd
path) all drives but one, and use trial and error to get the element right.
