Before you replicate the configuration of a Hitachi TrueCopy or Universal Replicator protection group to a secondary 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 group is set to False. You can view this property by using the clresourcegroup command.
# clresourcegroup show -p auto_start_on_new_cluster apprg
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.
Set the Auto_start_on_new_cluster property to False as follows:
# clresourcegroup set -p Auto_start_on_new_cluster=False apprg1
Log in to phys-newyork-1.
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.
phys-newyork-1 is the only node on the secondary cluster. For a reminder of which node is phys-newyork-1, see Example Sun Cluster Geographic Edition Cluster Configuration 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.
phys-newyork-1# geopg get -s partnershipname [protectiongroup]
Specifies the name of the partnership from which the protection group configuration information should be retrieved and the name of the partnership where the protection will be created locally.
Specifies the name of the protection group.
If no protection group is specified, then all protection groups that exist in the specified partnership on the remote partner are created on the local cluster.
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 tcpg from cluster-paris to cluster-newyork.
# rlogin phys-newyork-1 -l root phys-newyork-1# geopg get -s paris-newyork-ps tcpg
