Severity: 3-Major


The Nitrox PX encounters an error and proceeds to perform a soft reset, but if the soft reset fails, then there are no further attempts at recovery will be taken. The device will remain offline and no failsafe action will be triggered.


Whenever a Nitrox PX soft reset fails, the device is left offline and remain unusable until TMM is restarted or the BIG-IP system is rebooted. No retries are attempted even though the driver is designed to retry three times before triggering the failsafe action.


When a Nitrox PX device starts recovery and the soft reset procedure fails to complete successfully, the driver only logs the failure.


to recover service to the Nitrox PX devices once this occurs, issue the following command to restart tmm: bigstart restart tmm Note: Traffic will be disrupted while tmm restarts.

Fix Information

The system now triggers another reset sequence at the next opportunity when a soft reset fails.
