This read-create ZoneQosPriorityLevel object specifies the QoS priority value for this zone, relevant only when zoneQos is enabled by setting it to true. Admins set it to define the actual priority level enforced for the zone's members once QoS is turned on. For example, after enabling QoS on a zone for critical storage traffic, an admin would set this priority object to the highest available level to ensure that traffic gets preferential treatment.
