Bug ID 1967481: "Show cluster" may incorrectly log a system controller as not present

Last Modified: Oct 21, 2025

F5OS Velos(all modules)

Known Affected Versions:
F5OS-C 1.8.1, F5OS-C 1.8.2

Symptoms

When running "show cluster", it may show a message like this, even though a system controller is present: Controller 2 is NOT present. A service incorrectly reads that a system controller is not present, but correctly reads it as present immediately after.

Impact

This only causes a message to be logged and does not affect the stability of the chassis.

Conditions

This happens very rarely. There are no specific conditions that will cause this issue.

Workaround

None.
