114Veritas Cluster Server: Configuring Oracle VM Server for SPARC for high availabilityAbout Veritas Cluster Server configuration models in an Oracle VM Server for SPARC environment■Veritas Cluster Server setup to fail over an application on a failureSee “About Veritas Cluster Server in a Oracle VM Server for SPARC environment”on page 110.Veritas Cluster Server setup to fail over a logical domain on a failureYou can configure VCS to monitor the logical domain, or to monitor both thelogical domain and the application in the guest domain.■■See “Veritas Cluster Server installed in the control domain to monitor logicaldomains” on page 114.See “Veritas Cluster Server installed in the control domain to monitor theapplications in the guest domain” on page 115.When you configure VCS in the Oracle VM Server for SPARC environment, VCSmonitors the health of the logical domain, and its supporting components.VCSuses the LDom agent to monitor the logical domain and storage and networkagents to monitor storage and network services.If the agent detects that the logicaldomain resource has failed, VCS moves the service group that contains the logicaldomain resource to another node in the cluster.See the Veritas Cluster Server Bundled Agents Reference Guide for informationon the logical domain agent and other bundled agents.Veritas Cluster Server installed in the control domain to monitor logicaldomainsFigure 6-1 illustrates a typical setup where VCS installed in the control domainprovides high availability to the logical domain and it’s resources.
