Microsoft.SystemCenter.VirtualMachineManager.Storage.LUN.StorageLUNCapacityMonitor (UnitMonitor)

Knowledge Base article:

Summary

This monitor indicates if capacity usage of this LUN has exceeded its threshold.

Causes

This monitor shows that this Storage Logical Unit(LUN) is approaching its total capacity. The default thresholds are 80% consumed results in a warning state, and 90% consumed results in a critical state.

Resolutions

Based on the capabilities of the underlying array, either add additional space to the LUN or move the resources using it to another LUN.
