NetApp Aggregates at Risk
Use Search to find a template, report or dashboard by name. Search is case insensitive, supports partial entries, and will display a list of potential matches.
As you enter the name in the Search field, up to 10 potential matches are displayed. If the template, report or dashboard is shown, you can select and run it directly from the match list. You can also click All Items in the match list to go directly to the Search Results.
StorageConsole provides different navigation options to slice and examine your collected data. You can explore the data by using the APTARE customizable report templates or by using parts of your IT infrastructure as entry points. The Inventory Navigator serves as a browser for your infrastructure by object type.
Use the Reports tab to examine the StorageConsole catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. This report is located here:
Capacity Manager > Capacity At Risk > NetApp 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.
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 in order 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.
