Abstract

Embodiments of systems and methods to provide a firmware update to devices configured in a redundant configuration in an Information Handling System (IHS) are disclosed. In an illustrative, non-limiting embodiment, an IHS may include first and second Remote Access Controllers (RACs) that each includes computer-executable instructions to receive, by the first RAC, a firmware update image associated with the firmware device, and commence transfer of the firmware update image to the firmware device to perform a firmware update on the firmware device using an update mode that restricts another update request to the firmware device until the first RAC finishes or cancels the firmware update. When the transfer is halted prior to completion, the program instructions cause the second RAC to determine where the firmware update image transfer was halted, and commence transferring the remainder of the firmware update image that has not yet been transferred to the firmware device.
