Veritas™ File System 5.0.1 Administrator's Guide

In the following example, a file must reside in one of db/datafiles, db/indexes,
or db/logs and be owned by one of DBA_Manager, MFG_DBA, or HR_DBA to be
designated for possible action:
<SELECT>
<DIRECTORY Flags="nonrecursive">db/datafiles</DIRECTORY>
<DIRECTORY Flags="nonrecursive">db/indexes</DIRECTORY>
<DIRECTORY Flags="nonrecursive">db/logs</DIRECTORY>
<USER>DBA_Manager</USER>
<USER>MFG_DBA</USER>
<USER>HR_DBA</USER>
</SELECT>
If a rule includes multiple SELECT statements, a file need only satisfy one of them
to be selected for action. This property can be used to specify alternative conditions
for file selection.

Multiple placement classes in <ON> clauses of CREATE statements
and in <TO> clauses of RELOCATE statements
Both the <ON> clause of the CREATE statement and the <TO> clause of the RELOCATE
statement can specify priority ordered lists of placement classes using multiple
<DESTINATION> XML elements. VxFS uses a volume in the first placement class
in a list for the designated purpose of file creation or relocation, if possible. If no
volume in the first listed class has sufficient free space or if the file system's
volume set does not contain any volumes with that placement class, VxFS uses a
volume in the second listed class if possible. If no volume in the second listed class
can be used, a volume in the third listed class is used if possible, and so forth.
