1. A method comprising:
initiating, by a first management controller of a first compute node in an information handling system, a firmware update for firmware in a shared device of the information handling system, wherein the shared device is utilized by the first compute node and a second compute node;
detecting, by the first management controller, that the firmware update is complete;
in response to the firmware update being completed, sending rollback information for the firmware to a chassis controller of the information handling system; and
in response to reception of the rollback information, storing, by the chassis controller, the rollback information as a rollback image within a memory in the chassis controller.
