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.
  1. On the Vantage instance, open the following configuration file in a text editor: /etc/opt/teradata/tdconfig/nodestart.yaml.
  2. 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.
  3. Apply the configuration to all the nodes.
