How to Reboot a Cluster Node

1. If the cluster node is running Oracle Parallel Server/Real Application Clusters, shut down all instances of the database.

   Refer to the Oracle Parallel Server/Real Application Clusters 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.

   Enter these commands on the node to be shut down. The -i 6 option with the shutdown command causes the node to reboot after the node shuts down to the ok prompt.

   # scswitch -S -h node # shutdown -g0 -y -i6

   ---

   Note –

   Cluster nodes must have a working connection to the cluster interconnect to attain cluster membership.

   ---

4. Verify that the node has booted without error, and is online.

   # scstat -n

Example—Rebooting a Cluster Node

The following example shows the console output when rebooting node phys-schost-1. Messages for this node, such as shutdown and startup notification, appear on the consoles of other nodes in the cluster.

# scswitch -S -h phys-schost-1
# shutdown -g0 -y -i6
