Yes, you can supply the correct responses using something like:
ontape -a <<-! >>/export/home2/stu103/Llog 2>&1

See my response to Sadi G'rsoy.
I think what you are doing is VERY scary. For one, you have the
potential for trying to run multiple log backups simultaneously. For
two, the very next successful log backup will probably OVERWRITE the
previous log backup..., unless you are VERY quick (tape stacker?) at
removing that tape!

I would start with checking the status of ontape, but I don't know if it
reports success or failure correctly.
