add the three processes to the startup item at the end of the/etc/inittab file, so that Clusterware will be automatically started each time the system starts, if two processes run abnormally, EVMD and CRSD, the system automatically restarts the two processes. If the CSSD process is abnormal, the system restarts immediately.

Solution : Place a two-layer switch between the host and the layer three switch.

■ High Availability
To achieve high availability of Linux systems connected together in a cluster, by monitoring the health status of the system and applications, maintain customer connectivity and provide uninterrupted data access to any customer, regardless of the Internet, Intranet, or Internet. When the system goes down, the applications on the cluster can be automatical
