2.2.1 How to Shut Down a Cluster Node

1. (Optional). For a cluster node running Oracle Parallel Server (OPS), shut down all OPS database instances.

   Refer to the Oracle Parallel Server product documentation for shutdown procedures.

2. Become superuser on the cluster node to be shut down.

3. Shut down the cluster node by using the scswitch and shutdown commands.

   On the node to be shut down, enter the following command.

   # scswitch -S -h node # shutdown -g 0 -y

4. Verify that the cluster node has reached the ok PROM prompt.

5. If necessary, power off the node.

2.2.1.1 Example--Shutting Down a Cluster Node

The following example shows the console output when shutting down node phys-schost-1. The -g 0 option sets the grace period to zero, -y provides an automatic yes response to the confirmation question. Shutdown messages for this node appear on the consoles of other nodes in the cluster.

# scswitch -S -h phys-schost-1
# shutdown -g 0 -y
