Before You Begin
Before you switch over a protection group from the primary cluster to the secondary cluster, ensure that the following conditions are met:
For Oracle ZFS Storage Appliance, data replication is active between the primary cluster and the secondary cluster. That is, the replication is enabled from the source to the target appliances.
For Oracle ZFS Storage Appliance, the Geographic Edition replication resource for this appliance replication shows the Online state.
For Oracle Data Guard, the Oracle Data Guard Broker show configuration command shows a SUCCESS state. This state is reflected in the state of the Geographic Edition replication resource for this Oracle Data Guard Broker configuration, which should show the online state.
The Geographic Edition framework is running on both clusters.
The secondary cluster is a member of a partnership.
Both cluster partners can be reached.
The overall state of the protection group is set to OK.
If you use a role with Geo Management rights, ensure that the /var/cluster/geo access control lists (ACLs) are correct on each node of both partner clusters. If necessary, assume the root role on the cluster node and set the correct ACLs.
# chmod A+user:username:rwx:allow /var/cluster/geo
The /var/cluster/geo directory must have the correct ACL applied for compatibility between the Geo Management rights profile and Oracle ZFS Storage Appliance software.
Caution - For EMC SRDF, if you have configured the Cluster_dgs property, only applications that belong to the protection group can write to the device groups specified in the Cluster_dgs property.
The application resource groups that are a part of the protection group are stopped and started during the switchover.
phys-paris-1# geopg switchover [-f] -m new-primary-cluster protection-group-name
Forces the command to perform the operation without asking you for confirmation.
Specifies the name of the cluster that is to be the new primary cluster for the protection group.
Specifies the name of the protection group.
The following example performs a switchover to the secondary cluster cluster-newyork.
phys-paris-1# geopg switchover -f -m cluster-newyork example-protection-group
