3188577

Description: Some firmware scratchpad registers have been moved to a different location. Therefore, if you use your own utility to dump mstregdumps, you must update your CSV file with the latest CSV, CSV2 files that are included in the MFT package.

Otherwise, the mstregdumps device will not retrieve the firmware version, and the FAEs will not be able to use NVIDIA internal tools to debug the error.

Workaround: N/A

Keywords: CSV, mstregdump

Discovered in Version: 4.22.0

Workaround: To resolve the issue, run the following:

  1. opensm & (Press 'Enter')

  2. mst restart;

  3. mst ib add;

  4. mst status;

  5. Get the correct LID device from "InBand" devices
