You can replicate the configuration of a protection group to the partner cluster either before or after you configure data replication, resource groups, and resources on both clusters.
Before you replicate the configuration of a Sun StorageTek Availability Suite protection group to a partner cluster, ensure that the following conditions are met:
The protection group is defined on the remote cluster, not on the local cluster.
The device groups in the protection group on the remote cluster exist on the local cluster.
The application resource groups in the protection group on the remote cluster exist on the local cluster.
The Auto_start_on_new_cluster property of the resource groups is set to False. You can view this property by using the clresourcegroup show command.
# clresourcegroup show -p auto_start_on_new_cluster apprg
Set the Auto_start_on_new_cluster property to False as follows:
# clresourcegroup set -y Auto_start_on_new_cluster=False apprg1
Setting the Auto_start_on_new_cluster property to False prevents the Sun Cluster resource group manager from automatically starting the resource groups in the protection group. Therefore, after the Sun Cluster Geographic Edition software restarts and communicates with the remote cluster to ensure that the remote cluster is running and that the remote cluster is the secondary cluster for that resource group. The Sun Cluster Geographic Edition software does not automatically start the resource group on the primary cluster.
Application resource groups should be online only on primary cluster when the protection group is activated.

You must be assigned the Geo Management RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.
Replicate the protection group configuration to the partner cluster by using the geopg get command.
This command retrieves the configuration information of the protection group from the remote cluster and creates the protection group on the local cluster.
# geopg get -s partnershipname AVSprotectiongroup
Specifies the name of the partnership from which the protection group configuration information is gathered
Specifies the name of the protection group
The geopg get command replicates Sun Cluster Geographic Edition related entities. For information about how to replicate Sun Cluster entities, see Replicating and Upgrading Configuration Data for Resource Groups, Resource Types, and Resources in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.
This example replicates the configuration of avspg to cluster-newyork.
The configuration of the protection group is retrieved from the remote cluster, in this example cluster-paris, and then validated by the data replication subsystem on the local cluster, cluster-newyork.
If the validation is successful, the Configuration status is set to OK and the protection group is created on the local cluster. This protection group contains a device group and an application group that are configured almost identically to the device group and application group on the remote cluster.
If the validation fails, the protection group is not created on the local cluster. Fix the cause of the error and replicate it again.
