問題

QoS latency is seen on volumes without a QoS policy.
This issue may also occur if Data Protection Optimized (DPO) QoS policies are configured.DPO creates SVM level policies with the name "dpo" in the QoS policy.
The license being applied may cause this inadvertantly, but the SVM level QoS policies are the trigger of this bug.
Latency associated with this issue may vary; some environments may see seconds of latency in some scenarios.
