Abstract: A method, system, and computer usable program product for updating firmware without disrupting service are provided in the illustrative embodiments. An updated firmware code is sent to a first firmware component and a second firmware component. The first firmware component is a primary firmware component and the second firmware component is a backup firmware component in a redundant firmware configuration. The updated firmware code is installed in second firmware component. The updated firmware code is activated in a third firmware component. The third firmware component is in communication with the first firmware component. A fail-over from the first firmware component to the second firmware component is performed such that a user communicating with the data processing system and receiving a service using the first firmware component continues to receive the service using the second firmware component without a disruption in the service.
