This rule relocates files smaller than 10 megabytes to tier1 volumes, files between
10 and 100 megabytes to tier2 volumes, and files larger than 100 megabytes to
tier3 volumes. VxFS relocates all qualifying files that do not already reside on
volumes in their DESTINATION placement classes when the fsppadm enforce
command is issued.
