Abstract
Systems and methods provide witness sled hardware installed in a chassis and updates to firmware used by the witness sled, where the updates are made using management resources of the chassis. A chassis may include data storage devices and Information Handling Systems (IHSs), each storing data redundantly to the storage devices, such in a vSAN. The witness sled provides witness functions, such arbitrating discrepancies in the redundantly stored data. The chassis includes a chassis management controller (CMC) that generates a mapping of baseline firmware in use by the witness sled. When a received firmware is an update to the baseline firmware and is not duplicative of a pending update, the CMC establishes a connection with a microcontroller of the witness sled over a management signaling pathway and transmits instructions and the received firmware update to the microcontroller, such that the programmed microcontroller updates the firmware of the witness sled.
