Abstract
A mechanism is provided for saving power in redundant service processors of the data processing system. A redundant service processor places a plurality of components into a low power state in response to receiving a primary control signal from a primary service processor within a first predetermined time period. The redundant service processor monitors for a signal within a second predetermined time period from the primary service processor. The redundant service processor determines whether the signal is a heartbeat signal or an activate signal in response to receiving the signal from the primary service processor within the second predetermined time period. Responsive to receiving the activate signal, the redundant service processor wakes-up the plurality of components that are in the low-power state in order for the redundant service processor to collect data and recover the data processing system in an event of a failure.
