Fixed In:

Opened: Jun 01, 2021

Severity: 3-Major


A mismatch between the running-configuration (i.e. what is returned by "tmsh list ...") and the saved-configuration (i.e. what is stored in the flat configuration files) for a partition other than /Common, despite a "tmsh save config" operation was just performed (either by the user or as a result of a config-sync).


Should a BIG-IP Administrator notice the mismatch, the only immediate impact is confusion as to why the config save operation was not effective. However, as the flat config files are now out-of-date, performing a config load operation on a unit in this state will resurrect old configuration objects that had been previously deleted. On an Active unit, this may affect traffic handling. On a redundant pair, there is the risk that the resurrected objects may make it to the Active unit after a future config-sync operation.


- One or more partitions other than /Common exist on the system. - One or more of said partitions have no more configuration objects defined in them (i.e. are empty). - A config save operation similar to "tmsh save sys config partitions { Common part1 [...] }" occurs, either manually initiated by an Administrator or as a result of a config-sync operation (in which case the device-group must be configured for manual synchronization).


If you notice the mismatch, you can resolve it by performing a config save operation for all partitions (i.e. "tmsh save sys config").

Fix Information

Non /Common partitions now get saved to disk as intended.
