From the ONTAP tools Home page, click Settings.
Click Unified Appliance Settings.
Specify the percent values for the Nearly full threshold (%) field and the Full threshold (%) field for both the volume alarm thresholds and the aggregate alarm thresholds.

While setting the values, you must keep the following information in mind:
- Clicking Reset resets the thresholds to the previous values.
  
  Clicking Reset does not reset the thresholds to the default values of 80 percent for “Nearly full” and 90 percent for “Full”.
- There are two ways to set the values:
  - You can use the up and down arrows next to the values to adjust the threshold values.
  - You can slide the arrows on the track bar below the values to adjust the threshold values.
- The lowest value that you can set for the Full threshold (%) field for volumes and aggregates is 6 percent.
After specifying the required values, click Apply.

You must click Apply for both volume alarm and aggregate alarm.
