Do not use send brk on a cluster console to shut down a cluster node. The command is not supported within a cluster.
SPARC: If your cluster 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.
Become superuser on the cluster node to be shut down.
Switch all resource groups, resources, and device groups from the node being shut down to other cluster members.
On the node to be shut down, type the following command.
# scswitch -S -h node |
Evacuates all device services and resource groups from the specified node.
Specifies the node from which you are switching resource groups and device groups.
Shut down the cluster node.
On the node to be shut down, type the following command.
# shutdown -g0 -y -i0 |
Verify that the cluster node is showing the ok prompt or the Select (b)oot or (i)nterpreter prompt on the Current Boot Parameters screen.
If necessary, power off the node.
The following example shows the console output when shutting down node phys-schost-1. The -g0 option sets the grace period to zero, -y provides an automatic yes response to the confirmation question, and -i0 invokes run level 0 (zero). Shutdown messages for this node appear on the consoles of other nodes in the cluster.
