By default, an instance continues to run after a node failure. You can configure an instance to stop or terminate before a node failure.
Node failure recovery is supported only for systems with three or more nodes.
- On the VantageCloud instance, open the following configuration file in a text editor: /etc/opt/teradata/tdconfig/nodestart.yaml.
- Change instance_state to stop, terminate, or running.For example, change this setting as follows to automatically terminate the instance when a node fails:
instance_state: terminate
If an instance state is changed to stop or terminate on node crash, crashdumps are not available for problem root cause analysis. - Apply the configuration to all the nodes.
