Abstract
Provided are a method, system, and article of manufacture for synchronizing controller firmware download. A master device controller receives a code download and sends the code download to a subordinate device controller. The master device controller requests a subordinate code status from the subordinate device controller indicating a status of the code download at the subordinate device controller and stores the received code download and a master code status for the download. The master device controller receives the subordinate code status from the subordinate device controller and compares the subordinate code status with the master code status to determine whether both are valid and at same code level. The master device controller updates the master code image with the code download and coordinating the update of the code download to the subordinate code image in response to determining that the master and subordinate code status are both valid and at the same code level.
