Use this procedure to restart an application on the original primary cluster and use the current data on the original primary cluster. Any updates that occurred on the secondary cluster while it was acting as primary are discarded.
The failback procedures apply only to clusters in a partnership. Perform the following procedure only once per partnership.
Before You Begin
Ensure that the clusters have the following roles:
If the original primary cluster had been down, the cluster is booted and the disaster recovery framework is enabled on the cluster. For more information about booting a cluster, see Booting a Cluster in Administering the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.
The protection group on the current primary cluster has the primary role.
The protection group on the original primary cluster has either the primary role or secondary role, depending on whether the original primary can be reached during the takeover from the current primary.
This procedure uses the example names cluster-paris for the original primary cluster and cluster-newyork for the current primary cluster.
The package is created on the original primary appliance, paris. The corresponding package is created on the original secondary appliance, newyork.
phys-newyork-1# geopg stop -e local protection-group
Specifies the scope of the command. By specifying a local scope, the command operates on the local cluster only.
Specifies the name of the protection group.
phys-paris-1# geopg takeover protection-group
phys-newyork-1# geopg update protection-group
Ensure that the protection group is not in an error state. A protection group cannot be started when it is in a error state.
phys-paris-1# geopg validate protection-group
For more information, see Validating a Protection Group in Installing and Configuring the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.
phys-paris-1# geopg start -e global protection-group
The protection group on cluster-paris now has the primary role, and the protection group on cluster-newyork has the role of secondary. The application services are now online on cluster-paris.
