Re: Problems with writing to manual 8mm tape drive

Your on the right track, but you need to set the 8mm as a different type of
tape drive.

In SMIT you need to add an adsm device, with the mt point of \dev\mtx, x being
the number of the device on \dev\rmtx.  This will create another definition,
I'm not an AIX guru.  Then delete your current 8mm drive inside adsm, and
redefine it as a 8mm tape using the mount point on \dev\mtx.  When you query
the drive after that it should be listed as a 8mm tape and not generic tape.
Generic tape is, afaik, a NT thing.

E'mail direct if you have some more questions.
