BIG-IP LTM(all modules)

Opened: Jun 23, 2022
Severity: 3-Major


Traffic across the entire chassis will be disrupted. /var/log/ltm will show a message from clusterd such as "Marking slot <nr> SS_FAILED". In "tmsh show sys cluster", blade availability will be "unknown" and clusterd state will be "shutdown".


Traffic will not be forwarded across the entire chassis.


-- A chassis platform. -- Clusterd heartbeats from a remote blade fail to arrive. This can happen for many reasons such as Linux kernel driver issues.


Reboot the blade in the failed state.
