During an HA failover of system controllers, it was observed that an system controller failover may take up to one minute.
A delay in system controller switchover negatively impacts system controller LACP (LACPD will only send PDUs from the active SC). This can cause problems with tenant HA, which sends HA to keep alive messages over the system controller control plane network.
System controllers failovers that are initiated by termination/restart of the vcc-confd container on the currently active system controller.
Execute the system redundancy go-standby command to perform an HA switchover prior to rebooting the active system controller.
During an system controller failover initiated by rebooting the active system controller, it takes 3 to 5 seconds for the ConfD Active role to change to the other system controller.
