@Na Zhu, currently OVN is not designed/implemented to have this kind of timeout mechanism.
It seems to be a valid request. At least it would be useful to be able to tell from OVN point of view if a Chassis in sb ovsdb is connected or not. This would require a service in OVN to be able to detect and update some status in sb ovsdb. One possible way may be to monitor the ovsdb connection status. However, this is not something to be supported in networking-ovn plugin. We will discuss in OVN community.
