I am running ADSM HSM.  After losing a disk I had to do a complete restore of
a filesystem.  I followed the instructions in the HSM manual on restoring an
entire file system, and this is what I did:

        recreate filesystem
        dsmc restore -dirsonly /monitor
        dsmmigundelete /monitor
        dsmc restore -replace=no -subdir=yes /monitor

After the file system was restored I did a 'dsmls' and saw that the stub files
are now 511K instead of what it was, 4095K.  I have no problem restrieving
the migrated files.  In fact, after a file is retrieved and then migrated again
the stub file returns to 4095K.  Everything is in order but I am just
wondering why the size of the stub files changed.  Is this normal?
