Veritas File System 5.0 Administrator's Guide (September 2006)

This criterion is met when files are unmodified for a designated
period or during a designated period relative to the time at which
the fsppadm enforce command was issued.
<MODAGE>
This criterion is met when files exceed or drop below a designated
size or fall within a designated size range.
<SIZE>
This criterion is met when files exceed or drop below a designated
I/O temperature, or fall with in a designated I/O temperature range.
A file's I/O temperature is a measure of the I/O activity against it
during the period designated by the <PERIOD> element prior to
the time at which the fsppadm enforce command was issued.
<IOTEMP>
This criterion is met when files exceed or drop below a specified
average access temperature, or fall within a specified access
temperature range. A file's access temperature is similar to its I/O
temperature, except that access temperature is computed using
the number of I/O requests to the file, rather than the number of
bytes transferred.
