Disaster Recovery Framework Resource Groups

When you enable the disaster recovery framework, the following Oracle Solaris Cluster resource groups are created:

  • geo-clusterstate – A scalable resource group that the disaster recovery framework uses to distinguish between node failover and cluster reboot scenarios.The resource group contains the following resources:

    • geosource geo-init-svc– Initialization service for the Oracle Solaris Cluster disaster recovery framework.

    • geo-zc-sysevent - (For zone clusters only) Runs resource methods in the global zone when the disaster recovery framework is started in a non-global zone. It manages the mechanism which transfers cluster events to subscribers in the zone cluster.

  • geo-infrastructure – A failover resource group that encapsulates the disaster recovery framework. The resource group contains the following resources:

    • geo-cluster-name – The logical hostname for the disaster recovery framework. The disaster recovery framework uses the logical hostname of a cluster for intercluster management communication and heartbeat communication. An entry in the naming services must be the same as the name of the cluster and be available on the namespace of each cluster.

    • geo-hbmonitor – Encapsulates the heartbeat processes for the disaster recovery framework.

    • geo-failovercontrol – Encapsulates the disaster recovery framework itself. The disaster recovery framework module uses this resource to load into the common agent container.

These resources are for internal purposes only, so you must not change them.

These internal resources are removed when you disable the disaster recovery framework.

You can monitor the status of these resources by using the clresource status command. For more information about this command, see the clresource(8CL) man page.
