2.1.1 How to Shut Down a Cluster

1. (Optional). For a cluster 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 a node in the cluster.

3. Shut down the cluster immediately by using the scshutdown(1M) command.

   From a single node in the cluster, enter the following command.

   # scshutdown -g 0 -y

4. Verify that all nodes have reached the ok PROM prompt.

5. If necessary, power off the nodes.

2.1.1.1 Example--Shutting Down a Cluster

The following example shows the console output when stopping normal cluster operation and bringing down all nodes to the ok prompt. The -g 0 option sets the shutdown grace period to zero, -y provides an automatic yes response to the confirmation question. Shutdown messages also appear on the consoles of the other nodes in the cluster.

# scshutdown -g 0 -y
