摘要： 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.

摘要： Disclosed is a computer implemented method and apparatus for establishing a redundant channel from an application to a peer data processing system. The interrupt-driven hot standby program receives, through the operation of a data processing system, a communication channel status corresponding to an application. The application has a first channel using local access across a first physical conduit to a first switch. In addition the communication channel status is, in part, an interrupt. The interrupt-driven hot standby program determines whether the redundant channel is present. The redundant channel is configured to use a second physical conduit distinct from the first physical conduit for traffic of the application. Responding to a determination that the redundant channel is present, the interrupt-driven hot standby program determines whether the redundant channel is configured to use the second physical conduit as local access to a redundant switch, wherein the redundant switch is not the first switch. The interrupt-driven hot standby program responds to a determination that the redundant channel is configured to use the second physical conduit by updating a communication channel list to include at least one attribute of the redundant channel, wherein the communication channel list is resident in the data processing system.

摘要： A method for enabling a Node Controller (NC), which claims a duplicate or invalid service processor Node Controller Identification (NCID) in a distributed service processor system, to be integrated into the system includes reading an NCID by the NC after the NC is booted, saving the NCID into a non-volatile storage and broadcasting an NC Present Message (NPM) to a System Controller (SC) repeatedly until the SC initiates communication, updating the NCID for the NC in the non-volatile storage when the NC receives an NCID change message from the SC and rating any future NPM as a new NCID, and checking a record of a new NC when the SC receives the NPM from the NC. If the SC has a record of a recorded NC with the same NCID as the new NC, then the SC checks its role as a primary SC. If the SC does not have the record of the recorded NC with the same NCID as the new NC, then the SC checks validity of the NCID.
