Abstract
A firmware update of multiple processing nodes in an information handling system may include writing updated firmware images to reserve memory partitions associated with each node, rolling all nodes back to the existing firmware images if writing of an updated firmware image fails, booting each node into the updated firmware image stored on its associated reserve memory partition if writing of updated firmware images succeeds, booting each node into the updated firmware image stored on its associated reserve memory partition, rolling all nodes back to the existing firmware images if booting of an updated firmware image fails, copying the updated firmware images from reserve memory partitions associated with each node to the respective working memory partition associated with each node if booting of updated firmware images succeeds.
