At the moment, I am setting up an OPM 1.1 system to monitor 2 clusters running Clustered ONTAP 8.2.1. Adding the clusters was easy, but after the initial 15 minute discovery, every volume on the cluster had the message "Performance Manager is unable to add this volume to the default policy group." Therefore, no performance data was monitored. None of the possible reasons given made any sense, there were no SVM, LUN or File objects in existing policy groups. In fact, there were no policy groups at all on these 2 clusters.
I worked around it by creating a policy group on every SVM with an unlimited workload, and adding all volumes of that SVM to the new policy group. Now OPM can monitor the volumes just fine, but the question remains why all volumes were not automatically added to the "default policy group" as they were supposed to. The "default policy group", by the way, appears to be invisible to the regular administrator... "qos policy-group show" only returns my own created policy groups.
