Opened: May 09, 2022

Severity: 3-Major


BIG-IP tenant software running on an F5OS device performs an MCPD "forceload" operation after a reboot which means the MCPD loads the configuration from the text config file rather than the binary database. /var/log/ltm contains chmand Hardware/Chassis change detected. Forcing db load from file


- Devices report "changes pending" after the tenant is rebooted. - This may result in configuration loss if auto-sync is configured. - This may result in configuration loss as a result of operational foul-ups, regardless of which device had a newer configuration before one was rebooted, the newly-rebooted device will claim to have a newer configuration.


The management mac address transfers from F5OS to BIG-IP tenant are not in sync.


A future update to F5OS will fix the issue
