Comment 0 for bug 1901604

The Adaptive QoS feature was introduced on ONTAP 9.3 [0], and its support for FlexVols were added on ONTAP 9.4.

The current driver does not validate ONTAP version when assigning an Adaptive QoS policy group to a LUN or a FlexVol, and it only raises an error when the ZAPI call is issued.

The error message is not very helpful for investigating the issue.

Expected result:
If an Adaptive QoS operation is requested on a non-supported ONTAP version, raise a helpful exception such as "NetAppException: Adaptive QoS not supported on this back end ONTAP version.".

Actual results:
The API request fails with the following error message:

    cinder.volume.drivers.netapp.dataontap.client.api.NaApiError: NetApp API failed. Reason - 13115:Extra input: qos-adaptive-policy-group
