When a farm operation succeeds:
The Control Center shows a completed status in the Message section of the Farm Request dialog of the Administration screen.
The farm –l farm_ID command shows an ERROR of 0 and the farm state will reflect the desired state for that operation.
When a farm operation fails:
The Control Center shows a failed status in the Message section of the Farm Request dialog of the Administration screen.
The farm ERROR is a nonzero number (other than 1000) and the farm is not in the desired state. An ERROR of 1000 is not an error; it means that a farm operation is in progress.
