The creation of QoS policies at cluster level is only possible via the cluster level credentials. GET IMO should be possible. But this needs to be double checked.\n\nAnother thing is, we are calling this capability netapp_cluster_qos_policy_groups_used and netapp_cluster_qos_workloads_used while this may not be possible to be fetched via SVM level credentials. That handling is missing from the code. Ideally (and we may need to check if GET API for QoS with SVM credential works) if the SVM credentials work, these capabilities must just be called netapp_qos_workloads_used and netapp_qos_policy_groups_used.
