Disclosed is a method, system, program, and data structure for updating code in a first and second controllers. The first and second controllers are capable of accessing storage regions in a storage device. The first controller receives a code update and signals the second controller. Access to the first controller is disabled and the code update is applied to the first controller. In response to the signaling, the second controller receives commands directed to all of the storage regions during the code update to the first controller.
