DELETE statement
The DELETE file placement policy rule statement is very similar to the RELOCATE
statement in both form and function, lacking only the <TO> clause. File placement
policy-based deletion may be thought of as relocation with a fixed destination.
Note: Use DELETE statements with caution.
The following XML snippet illustrates the general form of the DELETE statement:
<DELETE>
<FROM>
<SOURCE>
<CLASS>...placement_class_name...</CLASS>
</SOURCE>
<SOURCE>
...additional placement class specifications...
</SOURCE>
</FROM>
<WHEN>...relocation conditions...</WHEN>
</DELETE>
A DELETE statement contains the following clauses:
An optional clause that contains a list of placement classes from whose
volumes designated files should be deleted if the files meet the
conditions specified in the <WHEN> clause. No priority is associated
with the ordering of placement classes in a <FROM> clause. If a file to
which the rule applies is located on a volume in any specified
placement class, the file is deleted. If a DELETE statement does not
contain a <FROM> clause, VxFS deletes qualifying files no matter on
which of a file system's volumes the files reside.
<FROM>
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>
