Last Modified: Nov 07, 2022

Bug Tracker

Affected Product:  See more info
F5OS Install/Upgrade(all modules)

Known Affected Versions:
1.2.0

Fixed In:
1.3.0, 1.2.1

Opened: Aug 23, 2021
Severity: 2-Critical

Symptoms

The upgrade proceeds to the point where both system controllers boot to the new image, but neither system controller becomes active.

Impact

Neither system controller becomes active, and the ability to configure the system controllers is compromised.

Conditions

When this issue is observed, the output of the "show full-configuration system redundancy config mode" command is something other than the default (auto).

Workaround

Restarting both Vcc-ConfD containers (or a reboot of both system controllers) should clear the problem.

Fix Information

Intermittent loss of active system controller when upgrading from F5OS-C 1.2.0-10357 to 1.2.1-10301 is now fixed in F5OS-C 1.2.1.
