When a farm update fails, changes do not always roll back to the last good state of the farm.
Workaround: The workaround for the problem is as follows:
To clear the error state, contact the farm using the farm -pf farm-ID command.
View the farm in the farm editor.
From the farm editor, select the latest farm update request from the Request History panel on the left. The correct farm information will display.
Choose Commit from the File menu to resubmit the farm update. A newly updated request is issued.
Unblock the new request. The correct farm information will display in the farm editor after the request is completed.
