106Veritas Cluster Server support for using CVM with multiple nodes in a Oracle VM Server for SPARC environmentCluster Volume Manager in the control domain for providing high availability6 If you want to monitor volumes, enter the following command:# # hares -modify name_of_resource CVMVolume -add \name_of_volumeIn a database environment, Symantec recommends you monitor volumes.7 Modify the resource so that a failure of this resource does not bring down theentire group:# hares -modify name_of_resource Critical 08 Enable the resources:# hares -modify name_of_resource Enabled 19 Make the configuration read-only:# haconf -dump -makero10 Verify the configuration:# hacf -verifyThis should put the resource in the main.cf file.Cluster Volume Manager in the control domain forproviding high availabilityThe main advantage of clusters is protection against hardware failure. Shouldthe primary node fail or otherwise become unavailable, applications can continueto run by transferring their execution to standby nodes in the cluster.CVM can be deployed in the control domains of multiple physical hosts runningOracle VM Server for SPARC, providing high availability of the control domain.Figure 5-1 illustrates a CVM configuration.

These applications can be failed over and restarted inside guests runningon another active node of the cluster.Caution: As such applications running in the guests may resume or time out basedon the individual application settings. The user must decide if the applicationmust be restarted on another guest on the failed-over control domain. There is apotential data corruption scenario if the underlying shared volumes get accessedfrom both of the guests simultaneously.Shared volumes and their snapshots can be used as a backing store for guestdomains.
