- Around line 282-302: Update the host firmware procedure around the Host
Firmware Config API to state that PUT only changes desired catalog state and
does not create a reprovisioning request. Explain that automatic selection
requires the applicable update policy and site capacity, while assigned hosts
require reboot approval or an autoreboot window; add links to the existing
automatic-update, host firmware reprovision request, and assigned-host approval
procedures, including the default disabled autoupdate behavior.
- Around line 289-292: Update the catalog-file documentation near the Cx7
artifact fields to explicitly require a 64-character lowercase hexadecimal
SHA-256 digest instead of the ambiguous “64-character sha256” wording.
- Around line 275-292: Update the firmware upgrade flow around upgrade.sh to
process every configured OPN/PSID artifact passed by Scout, rather than reading
only $1 and updating a single image. Ensure all CX7_<number> entries required by
the host are updated in order; alternatively, enforce and document a verified
combined image before allowing a single-artifact path.

NVIDIA DGX H100 H200 firmware update guide ConnectX-7 cluster storage OPN PSID separate firmware images
💡 Result:
To update the firmware on NVIDIA ConnectX-7 cards in an NVIDIA DGX H100 or H200 system, you must use specific, separate firmware images for the cluster and storage network cards, as they correspond to different Ordering Part Numbers (OPNs) and Parameter-Set Identifications (PSIDs) [1][2]. 1. Identify OPNs and PSIDs: Ensure you download the correct firmware for your specific card configurations [1][2]. Cluster network cards (e.g., OPN MCX750500B-0D00) typically use PSID MT_0000000891, while storage network cards (e.g., OPN MCX755206AS-NEA) typically use PSID MT_0000000892 [1]. Verify these values against the official NVIDIA documentation for your specific DGX model [1][2]. 2. Download Firmware: Obtain the appropriate firmware ZIP files from the official NVIDIA networking firmware download page (https://network.nvidia.com/support/firmware/connectx7ib/) [1][2]. 3. Update Procedure: - Transfer the extracted firmware files to the DGX system [1][2]. - Use the mlxfwmanager tool (part of the MLNX_OFED stack) to apply the firmware updates [1][2]. If MLNX_OFED is not available, the mstflint tool can be used with the burn command [1][2]. - You must perform the update separately for the cluster cards and the storage cards, providing the specific firmware binary file for the corresponding device identifiers [1][2]. 4. Finalize: - After updating, perform an AC power cycle on the DGX system for the changes to take effect [1][2]. - Once the system has rebooted, verify that all cards are running the same, correct firmware version by checking the firmware version string, typically located at /sys/class/infiniband/mlx5_*/fw_ver [1][2]. Updating ConnectX-7 devices on these systems generally requires approximately 30 minutes [3][4]. Always consult the official NVIDIA DGX H100/H200 Firmware Update Guide for your specific software version to ensure you are using the latest recommended firmware and procedures [1][2][5].

Process every required OPN/PSID artifact.
Scout downloads all configured artifacts and passes them to upgrade.sh in order, but the script reads only $1 and updates only that image. Because DGX H100/H200 cluster and storage CX7 cards require separate images, an artifact list can leave later CX7_<number> entries unchanged. Update the script to process every artifact, or document and enforce a verified combined image.

Document how the catalog change starts the update.
The PUT changes the desired catalog state; it does not itself create a host reprovisioning request. Automatic selection still depends on update policy and site capacity, and an assigned host needs reboot approval or an autoreboot window. (raw.githubusercontent.com) Add links to the existing automatic-update, host reprovision set, and assigned-host approval procedures. Otherwise an operator can publish the catalog and wait indefinitely when firmware_global.autoupdate is disabled, which is the documented default. (raw.githubusercontent.com)
As per path instructions, docs/** documentation must be technically correct and operator-usable.

Support all CX7 OPN/PSID variants.
The linked NVIDIA procedure requires selecting OPN and PSID values, then downloading firmware for both cluster and storage adapter variants. (docs.nvidia.com)
The packaged Scout upgrade.sh accepts one firmware file, excludes devices for which that file has no available image, and succeeds when at least one eligible device remains. (github.com)
Therefore, one configured artifact can leave a mixed-variant DGX H100 partially updated, while the all-entry verification in Lines 227-229 never succeeds. Document one artifact per required OPN/PSID and how Scout processes multiple artifacts, or explicitly restrict this procedure to hosts whose adapters share one compatible image.
