This read-create RowStatus object manages creation and deletion of rows in the PM instance table, per its description, set to 'createAndGo' to create a new instance and 'destroy' to remove one, with the index object cienaCesPmInstanceIndex specifying either a valid unused index or zero to auto-assign the next available one. This is the standard SNMP conceptual-row lifecycle control that turns a set of individual column values into an actual, active PM instance, or removes one entirely, rather than any of those columns individually. An automation script provisioning a new PM instance would set all the desired columns first and then set this object to createAndGo as the final step that actually instantiates the row.
