Abstract
An information handling system includes a shared device, first and second compute nodes, and a chassis management controller. The first compute node includes a first management controller, which initiates a firmware update for firmware in the shared device. The first management controller detects that that the firmware update is complete. In response to the firmware update being completed, the management controller sends rollback information for the firmware to the chassis controller. The chassis controller stores the rollback information as a rollback image within a storage location of a memory. The chassis controller further sends the rollback information to the second compute node. The second compute node includes a second management controller, which in turn receives the rollback information from the chassis controller, and updates the rollback information within the second compute node.
