You can shut down a node if it becomes unresponsive or if support personnel direct you to do so as part of troubleshooting efforts.
- To shut down a node, use the
system node halt command.
If you do not specify the -skip-lif-migration
parameter, the command attempts to migrate data and cluster management LIFs synchronously to another node prior to the shutdown. If the LIF migration fails or times out, the shutdown process is aborted, and Data ONTAP displays an error to indicate the LIF migration failure.
You can manually trigger a core dump with the shutdown by using both the -dump and -skip-lif-migration parameters.
Example of shutting down a node
The following example shuts down the node named "node1" for hardware maintenance:
cluster1::> system node halt -node node1 -reason 'hardware maintenance'
