Zone Clusters

A zone cluster is a cluster of Oracle Solaris non-global zones. You can use the clsetup utility or the Oracle Solaris Cluster Manager browser interface to create a zone cluster and add a network address, file system, ZFS storage pool, or storage device. You can also use a command line interface (the clzonecluster utility) to create a zone cluster, make configuration changes, and remove a zone cluster. For more information about using the clzonecluster utility, see the clzonecluster(8CL) man page. For more information about Oracle Solaris Cluster Manager, see Chapter 12, Using the Oracle Solaris Cluster Manager Browser Interface in Administering an Oracle Solaris Cluster 4.4 Configuration.

Supported brands for zone clusters are solaris, solaris10, and labeled. The labeled brand is used exclusively in a Trusted Extensions environment. To use the Trusted Extensions feature of Oracle Solaris, you must configure the Trusted Extensions feature for use in a zone cluster. No other use of Trusted Extensions is supported in an Oracle Solaris Cluster configuration.

You can also specify a shared-IP zone cluster or an exclusive-IP zone cluster when you run the clsetup utility.

Shared-IP zone clusters work with solaris or solaris10 brand zones. A shared-IP zone cluster shares a single IP stack between all the zones on the node, and each zone is allocated an IP address.
Exclusive-IP zone clusters work with solaris and solaris10 brand zones. An exclusive-IP zone cluster supports a separate IP instance stack.

Consider the following points when you plan the creation of a zone cluster:
