110Veritas Cluster Server: Configuring Oracle VM Server for SPARC for high availabilityAbout Veritas Cluster Server in a Oracle VM Server for SPARC environmentAbout Veritas Cluster Server in a Oracle VM Serverfor SPARC environmentVeritas Cluster Server (VCS) provides high availability (HA) for Oracle VM Serverfor SPARC. You can configure VCS to monitor the Logical Domain, services to theLogical Domain, and the applications that run in logical domain, or to monitoronly the applications that run in the logical domain.See “About Veritas Cluster Server configuration models in an Oracle VM Serverfor SPARC environment” on page 113.Table 6-1 lists the failure scenarios and the VCS failover options based on whichyou can plan your VCS configuration in an Oracle VM Server for SPARCenvironment.Table 6-1Veritas Cluster Server failover options for logical domain failureFailure scenarioLogical domains, theirstorage, or switches failVCS failoverVCS fails over the logicaldomain from one node toanother nodeTypical VCS configurationVCS is installed in the controldomain of each node.See “Veritas Cluster Serversetup to fail over a logicaldomain on a failure”on page 114.Logical domains, theirstorage, or switches failOrApplications that run inlogical domains failVCS fails over the logicaldomain from one nodeanother node.The application starts on thesame logical domain after thelogical domain failover.VCS is installed in the controldomain of each node, andsingle node VCS is installedon each guest domain.See “Veritas Cluster Serversetup to fail over a logicaldomain on a failure”on page 114.Applications that run inlogical domains failOrlogical domain where theapplication is running failsVCS fails over the applicationfrom one logical domain toanother.VCS is installed in the guestdomain of each node.See “Veritas Cluster Serversetup to fail over anapplication on a failure”on page 117.Veritas Cluster Server prerequisitesThis document assumes a working knowledge of VCS.
Veritas Cluster Server: Configuring Oracle VM Server for SPARC for high availabilityAbout Veritas Cluster Server in a Oracle VM Server for SPARC environment111Review the prerequisites in the following documents to help ensure a smooth VCSinstallation:■■Veritas Cluster Server Release NotesFind this in the cluster_server/docs directory of the product disc.Veritas Cluster Server Installation GuideFind this in the cluster_server/docs directory of the product disc.Unless otherwise noted, all references to other documents refer to the VeritasCluster Server documents version 5.1 SP1 for Solaris.Veritas Cluster Server requirementsFor installation requirements:See “System requirements” on page 79.For the configuration model where VCS is installed on the control domain:■■■VCS requires shared storage that is visible across all the nodes in the cluster.Configure Logical Domain on each cluster node.The logical domain’s boot device and application data must reside on sharedstorage.For the configuration model where VCS is installed on the guest domain:■■■Veritas Cluster Server limitationsVCS requires the application data to reside on the shared storage.Each node can have more than one logical domain.Each logical domain can have its own boot device.Depending on the configuration model, the following limitations apply to VCS inan Oracle VM Server for SPARC environment.Limitations for VCS configuration in the control domain:■Each logical domain configured under VCS must have at least two VCPUs. Withone VCPU, the control domain always registers 100% CPU utilization for thelogical domain. This is an Oracle VM Server for SPARC software issue.Limitation for VCS configuration in the guest domain:■Do not export a physical device to more than one guest domains on the samephysical node. For example: If you configure I/O fencing in guest domain, andif one of the guest domains dies, then I/O fencing fences off the other guestdomains as well.
