Is your copypool complete?  If somehow you missed copying the
files on the tape in question, then the server is correct.  Try this select
to check your copy pool --

select sum(num_files)
 from adsm.occupancy
  group by stgpool_name

The values for your on-site pools should add up to the values
for your offsite pool except for the files that have arrived since the
last 'ba stg' command.

I agree with the other who have replied, what IBM has told you
is wacky, they must be smoking some wierd tabacky.
