Systems and methods for updating witness sleds

A chassis management controller installed within a chassis comprising one or more Information Handling Systems (IHSs) and further comprising a plurality of data storage devices, the chassis management controller comprising:

• a logic unit;
• and
• a memory device having instructions stored thereon that, upon execution by the logic unit, cause the chassis management controller to:
• receive, from a first of the IHSs, an update to an operating system of a witness sled installed in the chassis and configured to arbitrate discrepancies in data redundantly stored in the plurality of storage devices;
• deconflict the received update with any pending updates to the witness sled operating system;
• and
• transmit, via a management coupling between the chassis management controller and the witness sled, the operating system update to the witness sled for use in arbitrating discrepancies in the data redundantly stored in the plurality of storage devices, wherein the management coupling comprises a signaling pathway used for Inter-Integrated Circuit (I2C) communications between the chassis management controller and an embedded management controller of the witness sled;
• wherein the chassis management controller is configured to emulate a Universal Serial Bus (USB) connection to the embedded management controller of the witness sled via the signaling pathway.

A non-transitory computer-readable storage device having instructions stored thereon for management of a chassis comprising one or more Information Handling Systems (IHSs) and further comprising a plurality of data storage devices, wherein execution of the instructions by one or more processors the chassis causes the one or more processors to:

• receive, from a first of the IHSs, an update to an operating system of a witness sled installed in the chassis and configured to arbitrate discrepancies in data redundantly stored in the plurality of storage devices;
• deconflict the received update with any pending updates to the witness sled operating system;
• and
• transmit, via a management coupling between a chassis management controller and the witness sled, the operating system update to the witness sled for use in arbitrating discrepancies in the data redundantly stored in the plurality of storage devices, wherein the management coupling comprises a signaling pathway used for Inter-Integrated Circuit (I2C) communications between the chassis management controller and an embedded management controller of the witness sled;
• wherein the chassis management controller is configured to emulate a Universal Serial Bus (USB) connection to the embedded management controller of the witness sled via the signaling pathway.
