Abstract
An apparatus, system, and method are disclosed for non-interruptively updating firmware on a redundant hardware controller. The apparatus includes a routing module, a receiving module, and a forwarding module. The routing module routes communications between a redundant hardware controller and a service processor associated with a flash update. The receiving module receives a flash command for the flash update from the service processor via a shared serial connection. The forwarding module forwards the flash command via a dedicated point to point connection to the redundant hardware controller configured to receive the flash command over the point to point connection. The apparatus, system, and method provide a non-interruptive overlay of the firmware image on a redundant hardware controller, minimizing system downtime and user intervention.
