Replicating the SRDF Protection Group Configuration to a Partner Cluster

Language:

After you have configured data replication, resource groups, and resources on your primary and secondary clusters and you have created a protection group for those entities on the primary cluster, you can replicate the configuration of the protection group to the secondary cluster.

How to Replicate the SRDF Protection Group Configuration to a Partner Cluster

Note - You can also accomplish this procedure by using the Oracle Solaris Cluster Manager browser interface. Click Partnerships, then click the partnership name. In the Protection Groups section, click Get Protection Groups and select the protection group to replicate. For more information about Oracle Solaris Cluster Manager, see Chapter 13, Using the Oracle Solaris Cluster GUI, in Oracle Solaris Cluster System Administration Guide .

Before You Begin

Before you replicate the configuration of an SRDF 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 system files on all nodes that can master the application have been updated for the application.
The application resource groups in the protection group on the remote cluster exist on the local cluster.
The HAStoragePlus resource exists in the application resource group to enable devices and mount file systems.

Log in to phys-newyork-1.
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 Geographic Edition Installation and Configuration Guide .

phys-newyork-1 is a node on the secondary cluster. For a reminder of which node is phys-newyork-1, see Example Geographic Edition Cluster Configuration in Oracle Solaris 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 partnership protection-group
```
–s partnership

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.

protection-group

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.

Note - The geopg get command replicates Geographic Edition related entities. To replicate Geographic Edition 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. Then 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 Software Installation Guide and the cluster (1CL) and clresource (1CL) man pages.

Example 10 Replicating the SRDF Protection Group to a Partner Cluster

This example replicates the configuration of srdfpg from cluster-paris to cluster-newyork.

# rlogin phys-newyork-1 -l root
phys-newyork-1# geopg get -s paris-newyork-ps srdfpg
