I was having the same trouble, still am actually,
thing is , I found that low density is 120meg and high is 150 meg.

I came to this conclusion looking through the doc from the
IBM AIX v3 System Administators class.

you need dc6150 tapes to get 150 meg on a tape, and you'll pay extra $$
for the extra 30 meg.
