Symptoms

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".

Impact

Traffic will not be forwarded across the entire chassis.

Conditions

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

Workaround

Reboot the blade in the failed state.
