Veritas File System 5.0 AdministratorÆs Guide, HP-UX 11i v3, First Edition, May 2008

DELETE elements, if any, are recommeded to preceed RELOCATE
elements, so that if a file is meant for deletion, will not
unnecessarily be subject relocation. The reason being,
if any of the DELETE elements triggers an action, subsequent
elements (DELETE and/or RELOCATE elements, if any) will not be
processed.

<!ELEMENT RULE (COMMENT?, SELECT+, CREATE?, DELETE*, RELOCATE*)>
<!-- The attributes of RULE element -->
<!-- The possible and accepted values for Flags are
1. data
2. checkpoint
The "data" is supported in 5.0 release. The "data" centric
RULEs deal with data of the files.
However "checkpoint" that is now introduced will allows
RULE specification to place data of the checkpoints
on a given set of placement classes. But in "checkpoint"
RULE only CREATE is supported, and DELETE and RELOCATE
are not supported, i.e., it is possible to direct the
data placement of the checkpoints that would be created
after such a placement policy becomes active but it is
not possible to relocate that of the already created
checkpoints.
