If you can't get mtx to compile on the AIX boxes so you can use 
chg-mtx, then you will have to do a bit of trickery in your scripts, 
using (it is available isn't it?) mt, because the chg-scsi script is 
a bit buggy, it never successfully issued a rewind cmd to the drive 
here at my place.   There for a while Thomas Hepper at a .de address 
was maintaining chg-scsi, but he hasn't checked in now in about 4 
years, so that bug hasn't been fixed.  Maybe you could fix it?

What this boils down to is that before you run amcheck or amdump, the 
tape must be rewound by some other means both before and after.  I 
don't know of the number of times amcheck would missfire because of 
that, and run all the way thru the rack looking for the right tape, 
when, if it would just reload the existing already loaded tape, which 
would fix the lack of rewind with only one io cycle on the robot 
instead of running thru the whole rack, and stopping on the tape 
before, making you run amcheck again just to load the right tape.  It 
appears amdump _can_ do a rewind after checking the label, but it 
must be handed a rewound tape up front as it will fail to verify the 
label if its left sitting at block one from the successfull amcheck 
run.

Good luck.

See above, build mtx on the AIX boxes and use chg-mtx.
