Enabling the Disaster Recovery Framework Infrastructure

Language:

When Disaster Recovery framework software is enabled, the cluster is ready to enter a partnership with another enabled cluster.

For more information about setting up and installing the Disaster Recovery framework, see Chapter 3, Administering the Disaster Recovery Framework in Administering the Disaster Recovery Framework for Oracle Solaris Cluster 4.4.

How to Enable the Disaster Recovery Framework

This procedure enables the Disaster Recovery framework infrastructure on the local cluster only. Repeat this procedure on all the clusters of your geographically separated cluster.

Before You Begin

Ensure that the following conditions are met:

The cluster is running the Oracle Solaris OS and Oracle Solaris Cluster software.
If you want to use the Oracle Solaris Cluster Manager browser interface to administer Disaster Recovery framework components, ensure that all cluster nodes have the same root password.
The Oracle Solaris Cluster management-agent container for Oracle Solaris Cluster Manager is running.
The Disaster Recovery framework software is installed.
The cluster has been configured for secure cluster communication by using security certificates, that is, nodes within the same cluster must share the same security certificates. This is configured during Oracle Solaris Cluster installation.

Assume the root role on a cluster node.
Ensure that the logical hostname, which is the same as the cluster name, is available and defined.
```
# cluster list
```
For global clusters, if the cluster name is not the name that you want to use, change the cluster name with the following command:
```
# cluster rename -c new-cluster-name cluster-name
```
-c new-cluster-name

Specifies the new cluster name.

cluster-name

The cluster whose name you are changing.

For more information, see the cluster(8CL) man page.

Note - After you have enabled the Disaster Recovery framework infrastructure, you must not change the cluster name while the infrastructure is enabled.
Confirm that the naming service and the local hosts files contain a host entry that matches the cluster name.
The local hosts file, hosts, is located in the /etc/inet directory.
On a node of the cluster, start the Disaster Recovery framework infrastructure.
```
# geoadm start
```
The geoadm start command enables the Disaster Recovery framework infrastructure on the local cluster only. For more information, see the geoadm(8) man page.
Verify that you have enabled the infrastructure and that the Disaster Recovery framework resource groups are online.
```
# geoadm show
# clresourcegroup status geo-clusterstate geo-infrastructure
# clresource status -g geo-clusterstate,geo-infrastructure
```
The output for the geoadm show command displays that the Disaster Recovery framework infrastructure is active from a particular node in the cluster.

The output for the clresourcegroup status and clresource status commands display that the geo-failovercontrol, geo-hbmonitor, and geo-clustername resources and the geo-infrastructure resource group is online on one node of the cluster. The geo-clusterstate resource group is online on both nodes.

For more information, see the clresourcegroup(8CL) and clresource(8CL) man pages.

Example 1 Enabling the Disaster Recovery Framework Infrastructure on a Cluster

This example enables the Disaster Recovery framework on the cluster-paris cluster.

Start the Disaster Recovery framework infrastructure on cluster-paris.
```
phys-paris-1# geoadm start
```

Ensure that the Disaster Recovery framework infrastructure was successfully enabled.

phys-paris-1# geoadm show

--- CLUSTER LEVEL INFORMATION ---
Oracle Solaris Cluster Disaster Recovery framework is active on cluster-paris from node phys-paris-1
Command execution successful
phys-paris-1#

Verify the status of the Disaster Recovery framework resource groups and resources.

phys-paris-1# clresourcegroup status geo-clusterstate geo-infrastructure
