There is nothing built in to TSM that does archiving based on last reference 
date.
You can certainly write your own scripts to select the files and archive based 
on that.

There are larger difference between archiving and HSM.
Archives:
-the same file can be archived multiple times on different dates
-an archive file may be left in the directory, or removed from the directory 
after archive
-to retrieve an archived file, you must deliberately open the TSM client and 
select the file for retrieve

HSM: 
-There is only 1 copy of an HSM-migrated file, the migrated copy.
-HSM leaves a stub file in the directory when it migrates the file out to TSM 
storage.  Any attempt by the user to reference that file triggers an automatic 
recall  (which has implications for your TSM hardware setup).

Does the archiving function allow archiving files based on last reference date 
or is that what TSM HSM is for ?
