When errors related to your implementation of Fault Tolerance are generated by vCenter Server, the Fault Details screen appears.

This screen lists faults related to Fault Tolerance and for each fault it provides the type of fault (red is an error, yellow is a warning), the name of the virtual machine or host involved, and a brief description.

You can also invoke this screen for a specific failed Fault Tolerance task. To do this, select the task in either the Recent Tasks pane or the Tasks & Events tab for the entity that experienced the fault and click the View details link that appears in the Details column.
