Last Updated:

Applies to

  • ONTAP 9.3 or later
  • Active IQ Unified Manager (AIQUM) 9.7 or later
  • Adaptive QoS (AQoS)
  • NetApp Service Level Manager (NSLM) 1.2 or later
  • Performance Service Level (PSL)
  • Workloads are created from NSLM or AIQUM

Issue

  • Workloads can be throttled by AQoS without manually creating an AQoS policy explicitly.
  • This unexpected AQoS policy attached to a workload might lead to high latency in the QoS Min delay center. 

Example:

Cluster::> qos statistics volume latency show
Workload             ID    Latency    Network    Cluster       Data       Disk    QoS Max    QoS Min      NVRAM
