Ah Ha!  You didn't say that you were using DOS under AIX!  The
SY-TOS utilities were developed for an operating system that does
not normally support tape devices (DOS).  You can contact Sytron at:

     Sytron Corporation
     135 Maple Street
     Marlboro, MA 01752

If you're going to back up AIX filesystems, you might do better with
the AIX backup or tar commands.  I admit that they're not as nice to
use as SY-TOS, but they work fairly well if you use a big enough block
size.  Another method that I've seen is to pipe the tar or backup output
through the 'dd' command to the tape drive.  'dd' seems to block things
a little better.  

Perhaps some AIX guru would be kind enough to give an exact sequence of
commands for this?
