NetApp Cluster-Mode Aggregates at Risk
For thin provisioning, it's important to know when host usage is about to exceed the storage that was promised. The details shown in this aggregate report can help you understand the current physical capacity status. When an aggregate is at risk--the amount of used storage in the FlexVol approaches the aggregate's capacity--it can be re-sized to add physical disk space to the aggregate. This is for Cluster Mode arrays.

Note:
The Total Capacity value represents the amount of storage that has been committed or promised to hosts. Therefore, host resources data collection must be implemented to determine which Aggregates are at risk and an associated host must be at risk in order for the Aggregate to be considered at risk.
When you generate this report, you can select the threshold to report: Low, Warning, or Critical.
