Sun Cluster Concepts Guide for Solaris OS

Support for Solaris Zones

Solaris zones provide a means of creating virtualized operating system environments within an instance of the Solaris 10 OS. Solaris zones enable one or more applications to run in isolation from other activity on your system. The Solaris zones facility is described in Part II, Zones, in System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.

When you run Sun Cluster software on the Solaris 10 OS, you can create any number of global-cluster non-voting nodes.

You can use Sun Cluster software to manage the availability and scalability of applications that are running on global-cluster non-voting nodes.

Support for Global-Cluster Non-Voting Nodes (Solaris Zones) Directly Through the RGM

On a cluster where the Solaris 10 OS is running, you can configure a resource group to run on a global-cluster voting node or a global-cluster non-voting node. The RGM manages each global-cluster non-voting node as a switchover target. If a global-cluster non-voting node is specified in the node list of a resource group, the RGM brings the resource group online in the specified node.

Figure 3–8 illustrates the failover of resource groups between nodes in a two-host cluster. In this example, identical nodes are configured to simplify the administration of the cluster.

You can configure a scalable resource group (which uses network load balancing) to run in a cluster non-voting node as well.

In Sun Cluster commands, you specify a zone by appending the name of the zone to the name of the host, and separating them with a colon, for example:

phys-schost-1:zoneA

Criteria for Using Support for Solaris Zones Directly Through the RGM

Use support for Solaris zones directly through the RGM if any of following criteria is met:

Requirements for Using Support for Solaris Zones Directly Through the RGM

If you plan to use support for Solaris zones directly through the RGM for an application, ensure that the following requirements are met:

If you use support for Solaris zones directly through the RGM, ensure that resource groups that are related by an affinity are configured to run on the same Solaris host.

Additional Information About Support for Solaris Zones Directly Through the RGM

For information about how to configure support for Solaris zones directly through the RGM, see the following documentation:

Support for Solaris Zones on Sun Cluster Nodes Through Sun Cluster HA for Solaris Containers

The Sun Cluster HA for Solaris Containers data service manages each zone as a resource that is controlled by the RGM.
