This section provides information about resynchronizing protection group information between partner clusters.
Partner clusters that become disconnected during a disaster situation might force the administrator to perform a takeover for a protection group that the partners share. When both clusters are brought online again, both partner clusters might report as the primary of the protection group. You must resynchronize the configuration information of the local protection group with the configuration information that is retrieved from the partner cluster.
You decide which protection group configuration information you want to keep: the information on the cluster that failed or the information on the partner cluster. Then, resynchronize the configuration of the protection group accordingly.
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 Oracle Solaris Cluster 4.3 Geographic Edition System Administration Guide.
Resynchronizing a protection group updates only entities that are related to Geographic Edition. 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 Oracle Solaris Cluster 4.3 Software Installation Guide and the cluster(1CL) and clresource(1CL) man pages.
Before You Begin
The protection group is be deactivated on the cluster where you run the geopg update command.
You must be assigned the Geo Management rights profile to complete this procedure. For more information, see Securing Geographic Edition Software in Oracle Solaris Cluster 4.3 Geographic Edition Installation and Configuration Guide.
# geopg update protection-group-name
Specifies the name of the protection group
