So, after reading that, I can understand why the question was asked.  That
didn't clear up anything.  Is a logical file the space defined for storing a
file and a physical file the actual physical space being used for that file?

The following definitions are taken from the Glossary
of the ADSM V3R1 Sun Solaris Admin Reference:

logical occupancy.  The space required for the storage
of logical files in a storage pool. Because logical occu-pancy
does not include the unused space created when
logical files are deleted from aggregates, it may be less
than  physical occupancy. See also  physical file and
logical file.

logical file.  A client file stored in one or more server
storage pools, either by itself or as part of an aggregate
file. See also  aggregate file and  physical file.

physical file.  A file, stored in one or more storage
pools, consisting of either a single logical file, or a group
of logical files packaged together (an aggregate file).
See also  aggregate file and  logical file.

physical occupancy.  The occupancy of physical files
in a storage pool. This is the actual space required for
the storage of physical files, including the unused space
created when logical files are deleted from aggregates.
See also  physical file,  logical file, and  logical occupancy.
