To add an existing application resource group to a new protection group without taking the application offline, complete the following steps on the cluster where the application resource group is online.
Create the protection group from a cluster node.

Add the data replication device group to the protection group.
For more information, see How to Add a Data Replication Device Group to a Hitachi TrueCopy or Universal Replicator Protection Group.
Start the protection group locally.
For more information, see How to Activate a Hitachi TrueCopy or Universal Replicator Protection Group.
Add the application resource group to the protection group.
For more information, see How to Add an Application Resource Group to a Hitachi TrueCopy or Universal Replicator Protection Group.
Complete the following steps on the other cluster.
Retrieve the protection group configuration.
For more information, see How to Replicate the Hitachi TrueCopy or Universal Replicator Protection Group Configuration to a Secondary Cluster.
Activate the protection group locally.

This example creates a protection group without taking the application offline.
In this example, the apprg1 resource group is online on the cluster-paris cluster.
Create the protection group on cluster-paris.
phys-paris-1# geopg create -d truecopy -p Nodelist=phys-paris-1,phys-paris-2 \ -o Primary -s paris-newyork-ps tcpg Protection group "tcpg" has been successfully created |
Add the device group, tcdg, to the protection group.
phys-paris-1# geopg add-device-group -p fence_level=async tcdg tcpg |
Activate the protection group locally.
phys-paris-1# geopg start -e local tcpg Processing operation.... this may take a while.... Protection group "tcpg" successfully started. |
Add to the protection group an application resource group that is already online.
phys-paris-1# geopg add-resource-group apprg1 tcpg Following resource groups were successfully inserted: "apprg1" |
Verify that the application resource group was added successfully.
phys-paris-1# geoadm status Cluster: cluster-paris Partnership "paris-newyork-ps" : OK Partner clusters : newyork Synchronization : OK ICRM Connection : OK Heartbeat "hb_cluster-paris~cluster-newyork" monitoring \ "paris-newyork-ps" OK Plug-in "ping-plugin" : Inactive Plug-in "tcp_udp_plugin" : OK Protection group "tcpg" : Degraded Partnership : paris-newyork-ps Synchronization : OK Cluster cluster-paris : Degraded Role : Primary Configuration : OK Data replication : Degraded Resource groups : OK Cluster cluster-newyork : Unknown Role : Unknown Configuration : Unknown Data Replication : Unknown Resource Groups : Unknown |
On a node of the partner cluster, retrieve the protection group.
phys-newyork-1# geopg get -s paris-newyork-ps tcpg Protection group "tcpg" has been successfully created. |
Activate the protection group locally on the partner cluster.
phys-newyork-1# geopg start -e local tcpg Processing operation.... this may take a while.... Protection group "tcpg" successfully started. |
Verify that the protection group was successfully created and activated.
Running the geoadm status command on cluster-paris produces the following output:
phys-paris-1# geoadm status Cluster: cluster-paris Partnership "paris-newyork-ps" : OK Partner clusters : newyork Synchronization : OK ICRM Connection : OK Heartbeat "hb_cluster-paris~cluster-newyork" monitoring \ "paris-newyork-ps": OK Plug-in "ping-plugin" : Inactive Plug-in "tcp_udp_plugin" : OK Protection group "tcpg" : Degraded Partnership : paris-newyork-ps Synchronization : OK Cluster cluster-paris : Degraded Role : Primary Configuration : OK Data replication : Degraded Resource groups : OK Cluster cluster-newyork : Degraded Role : Secondary Configuration : OK Data Replication : Degraded Resource Groups : OK |
