Resynchronizing a Protection Group

You can resynchronize the configuration information of the local protection group with the configuration information retrieved from the partner cluster. You need to resynchronize a protection group when its Synchronization status in the output of the geoadm status command or in Oracle Solaris Cluster Manager is Error. For example, you might need to resynchronize protection groups after booting the cluster. For more information, see Booting a Cluster in Administering the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.

Resynchronizing a protection group updates only entities that are related to the disaster recovery framework. To update Oracle Solaris Cluster resource groups, resource types, and resources, use the cluster export -t rg,rt,rs command to generate an XML cluster configuration file, modify the XML file for the expected configuration on the secondary cluster, and run the clresource create command with the –a option to apply the configuration updates. For more information, see How to Configure Oracle Solaris Cluster Software on All Nodes (XML) in Installing and Configuring an Oracle Solaris Cluster 4.4 Environment and the cluster(8CL) and clresource(8CL) man pages.

How to Resynchronize a Protection Group

Note -  You can also accomplish this procedure by using the Oracle Solaris Cluster Manager browser interface. Click Partnerships, click the partnership name to go to its page, highlight the protection group name, and click Update Protection Group. For Oracle Solaris Cluster Manager log-in instructions, see How to Access Oracle Solaris Cluster Manager in Administering an Oracle Solaris Cluster 4.4 Configuration.

The protection group must be deactivated on the cluster where you run the geopg update command.

  1. Log in to a cluster node.

    You must be assigned the Geo Management rights profile to complete this procedure. For more information, see Disaster Recovery Framework Rights Profiles in Installing and Configuring the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.
