What is chassisFanControllerVpdRevision?

This OCTET STRING is the firmware revision of the onboard controller chip on a chassis fan module, as distinct from the fan's separate hardware VPD data covering its manufacturer and serial number. An admin checks this revision before a firmware campaign to confirm whether a given fan's controller needs the update or already has it. For example, chassisFanControllerVpdRevision showing an older revision string on one fan while its neighbors show a newer string flags exactly which fan module still needs its controller firmware refreshed.
