This writable execute-only object resets all MM configuration to factory defaults (discarding all prior configuration) and restarts the MM, while preserving the existing logs; the GET value is meaningless. It's a drastic recovery action an admin would use when the MM's configuration is so corrupted or misconfigured that starting fresh is preferable to troubleshooting further, while still wanting to keep the event logs for post-mortem analysis. An admin dealing with a chassis stuck in a bad network state after a failed config change might trigger resetSPConfigAndRestartSaveLogs to wipe the bad config while retaining logs to diagnose what went wrong.
