Create a sample custom report to experience exploring views and scheduling reports. This quick start report finds a list of volumes that you might want to move to the cloud tier because there is a fair amount of inactive (cold) data. You will open the Performance: All Volumes view, customize the view using filters and columns, save the custom view as a report, and schedule the report to share once a week.
Based on the results shown in the report, you may want to use ONTAP System Manager or the ONTAP CLI to change the tiering policy to "auto" or "all" for certain volumes to offload more cold data to the cloud tier.
