Hi,
Can you please clarify if you are looking at 7-mode or Clustered Data ONTAP ?
Also, did you get a chance to look at the dictionary entries
Array_Performance and Aggregate_Performance in performance scheme (7-Mode) and Aggregate_Performance in cm_performance schema (Clustered Data ONTAP)
In order to get that populated, you would need to create data sources for Performance Advisor in the Data Sources screen.
Once that is done, you would need to use appropriate filters in your resource selection criteria of your workflow (Example filter: Filter aggregates in arrays with high disk throughput)
Thanks,
Shailaja
