Veritas Storage Foundation 5.1 SP1 Advanced Features Administrator"s Guide (5900-1503, April 2011)

An optional clause specifying the conditions under which files to which
the rule applies should be deleted. The form of the <WHEN> clause in
a DELETE statement is identical to that of the <WHEN> clause in a
RELOCATE statement. If a DELETE statement does not contain a
<WHEN> clause, files designated by the rule's SELECT statement, and
the <FROM> clause if it is present, are deleted unconditionally.
<WHEN>
DELETE statement examples
The following example illustrates the use of the DELETE statement:
<DELETE>
<FROM>
<SOURCE>
<CLASS>tier3</CLASS>
</SOURCE>
</FROM>
</DELETE>
<DELETE>
<FROM>
<SOURCE>
<CLASS>tier2</CLASS>
</SOURCE>
</FROM>
<WHEN>
<ACCAGE Units="days">
<MIN Flags="gt">120</MIN>
</ACCAGE>
</WHEN>
</DELETE>
The first DELETE statement unconditionally deletes files designated by the rule's
SELECT statement that reside on tier3 volumes when the fsppadm enforce
command is issued. The absence of a <WHEN> clause in the DELETE statement
indicates that deletion of designated files is unconditional.
The second DELETE statement deletes files to which the rule applies that reside
on tier2 volumes when the fsppadm enforce command is issued and that have
not been accessed for the past 120 days.
