Abstract
An apparatus, system, and method are disclosed for updating firmware to a plurality of memory devices residing on disparate controllers wherein each controller includes an identical communication path address. A management module writes a firmware image to a memory device residing on a primary controller. The primary controller, in turn, copies the firmware image to another memory device residing on a secondary controller. In this manner, the apparatus, system, and method may update firmware on a plurality of memory devices. Because the primary controller is tasked with updating the secondary controller, the management module is only aware that the firmware of the primary controller has been updated. In this manner, updating of the firmware on the secondary controller is transparent to the management module.
