Brett is almost right (sorry Brett :-)
The ADSM server shows only those objects (files and directories) on the
Q OCC command that have actual data stored in a storage pool.
  Before I go further, let me explain a few things:
   o  There are two major data areas in the ADSM server, 1. the Database and
      2. Data Storage (the storage pools).
   o  The Database contains object meta-data (i.e. name, last modification
      date, UID, GID, permissions, ...)
   o  Data Storage contains the actual object data, if any.  This includes
      file data, access control lists, the Mac resource forks, OS/2 extended
      attributes.  Basically anything associated with an object that can
      take up possibly a lot of storage.
Any object that doesn't have any data in Data Storage does not show up
in the output of the Q OCC command.
Examples:
   o  Most zero-length files, except on the Mac and Novell systems, which (I
      think, correct me if I'm wrong Brett and Frank) always have either
      resource forks or Netware SMS data.
   o  Most directories, except those with ACLs and EAs.  Again, the Mac
      and Novell systems I think always have data in Data Storage associated
      with all of their directories.
So, that is why you see two different numbers.  Q OCC only reports back what
is contained in Data Storage (storage pools).

I hope this clarifies this,
