How to Enable Sun Cluster Geographic Edition Software

Before You Begin

Before you enable Sun Cluster Geographic Edition software on a cluster, ensure that the following conditions are met:

• The cluster is running the Solaris Operating System and the Sun Cluster software.

• The Sun Cluster management-agent container for SunPlex Manager is running.

• The Sun Cluster Geographic Edition software is installed.

Steps

1. Log in to one of the cluster nodes.

   You must be assigned the Geo Operation RBAC rights profile to complete this procedure. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.

2. Ensure that the logical hostname, which is the same as the cluster name, is available and defined.

   # scconf -p | grep -i "cluster name"

   If the cluster name is not the name you want to use, you can change the cluster name with the following command:

   # scconf -c -C cluster=cluster-name

   For more information, see the scconf(1M) man page.

3. Confirm that a logical hostname that matches the cluster name is available and defined in the local host files.

   The local host file, hosts, is located in the /etc/inet directory.

   Confirm that the logical hostname is also defined in the network namespace database, for example, NIS.

4. On one node of the cluster, create the Sun Cluster Geographic Edition infrastructure resource groups and enable the Sun Cluster Geographic Edition control module.

   # geoadm start

   The geoadm start command enables the Sun Cluster Geographic Edition control module on the local cluster only. For more information, see the geoadm(1M) man page.

5. Verify that you have enabled the infrastructure and that the Sun Cluster Geographic Edition resource groups are online.

   # geoadm show # scstat -g

   The output for the geoadm show command should state that the Sun Cluster Geographic Edition infrastructure is active from a particular node in the cluster.

   The output for the scstat -g command should state that the geo-failovercontrol, geo-hbmonitor, and geo-clustername resources and the geo-infrastructure resource groups are online on one node of the cluster.

   For more information, see the scstat(1M) man page.

Example 3–1 Enabling a Cluster

The following example illustrates how to enable Sun Cluster Geographic Edition software on a cluster:

# geoadm start
# geoadm show
# scstat -g
