Working With a Zone Cluster

Two Sun Cluster administrative commands (cluster and clnode) can also run in a zone cluster. However, the scope of these commands is limited to the zone cluster where the command is issued. For example, using the cluster command in the global-cluster voting node retrieves all information about the voting global cluster and all the zone clusters. Using the cluster command in a zone cluster retrieves information about that specific zone cluster.

When you use the clzonecluster command in a voting node, the command affects all of the zone clusters in the global cluster. Zone cluster commands also affect all nodes on the zone cluster, even if the node is down when the command is issued.

Zone clusters support delegated administration of resources that are under Resource Group Manager (RGM) control. Therefore, zone cluster administrators can view, but not change, zone cluster dependencies that cross zone cluster boundaries. Only the administrator in a voting node can create, modify, or delete dependencies that cross zone cluster boundaries.

The following list contains the major administrative tasks performed on a zone cluster.

• Creating a zone cluster – Use the clzonecluster configure command to create a new zone cluster. See the instructions in Configuring a Zone Cluster in Sun Cluster Software Installation Guide for Solaris OS.

• Starting and rebooting a zone cluster – See Chapter 3, Shutting Down and Booting a Cluster.

• Adding a node to a zone cluster – See Chapter 8, Adding and Removing a Node.

• Removing a node from a zone cluster – See How to Remove a Node From a Zone Cluster.

• Viewing the configuration of a zone cluster – See How to View the Cluster Configuration.

• Validating the configuration of a zone cluster – See How to Validate a Basic Cluster Configuration.

• Stopping a zone cluster – See Chapter 3, Shutting Down and Booting a Cluster.
