I couldn't find this in info, but it is in some doc from the AIX
system administration class.

           /dev/rmtX.ABC
                   ^ ^^^

X = The order of the tape device on the system. (rmt0,rmt1,etc....)
A = Density
    1 = QIC120 = 120 meg \____ This is what the Student guide says
    2 = QIC150 = 150 meg /     but you will probably have to experiment.

B = Retension
    1 = YES
    2 = NO

C = Rewind on close
    1 = Do NOT Rewind
    0 = Rewind

-----
I have seen this error message when trying to use 60 meg tapes on
the streaming tape drive and using /dev/rmt1.1 worked for me.

give it a try.

hope this helps.
