How to Shut Down a Cluster

You can shut down a global cluster, a zone cluster, or all zone clusters.


Caution

Caution  -  Do not use send brk on a cluster console to shut down a global-cluster node or a zone-cluster node. The command is not supported within a cluster.


The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.

This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.

  1. (x86 only) If your global cluster or zone cluster is running Oracle Real Application Clusters (RAC), shut down all instances of the database on the cluster you are shutting down.

    Refer to the Oracle RAC product documentation for shutdown procedures.

  2. Assume the root role or a role that provides solaris.cluster.admin authorization on any node in the cluster.

    Perform all steps in this procedure from a node of the global cluster.

  3. Shut down the global cluster, the zone cluster, or all zone clusters.
    • Shut down the global cluster. This action also shuts down all zone clusters.
      phys-schost# cluster shutdown -g0 -y
    • Shut down a specific zone cluster.
      phys-schost# clzonecluster halt zone-cluster-name
    • Shut down all zone clusters.
      phys-schost# clzonecluster halt +

      You can also use the cluster shutdown command within a zone cluster to shut down that particular zone cluster.

  4. Verify that all nodes on the global cluster or zone cluster are showing the ok prompt on a SPARC based system or a GRUB menu on an x86 based system.

    Do not power off any nodes until all nodes are at the ok prompt on a SPARC based system or in a boot subsystem on an x86 based system.

    • Check the status of one or more global-cluster nodes from another global-cluster node which is still up and running in the cluster.
      phys-schost# cluster status -t node
    • Use the status subcommand to verify that the zone cluster was shut down.
      phys-schost# clzonecluster status
  5. If necessary, power off the nodes of the global cluster.
Example 13  Shutting Down a Zone Cluster

The following example shuts down a zone cluster called sczone.

phys-schost# clzonecluster halt sczone
Waiting for zone halt commands to complete on all the nodes of the zone cluster "sczone"...

Example 14  SPARC: Shutting Down a Global Cluster

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

phys-schost# cluster shutdown -g0 -y

Example 15  x86: Shutting Down a Global Cluster

The following example shows the console output when normal global-cluster operation is stopped and all nodes are shut down. In this example, the ok prompt is not displayed on all of the nodes. The –g 0 option sets the shutdown grace period to zero, and the -y option provides an automatic yes response to the confirmation question. Shutdown messages also appear on the consoles of the other nodes in the global cluster.
