ONTAP 9 Manuals ( CA08871-402 )

The priority is used when multiple policies are enabled on the storage virtual machine (SVM) and more than one policy has subscribed to the same file access event.

Policies that use the native engine configuration have a higher priority than policies for any other engine, regardless of the sequence number assigned to them when enabling the policy.

If you want to change the priority of an FPolicy policy, you must disable the policy and then reenable it using the new sequence number.
