3. Run the following command to apply the configuration file:
cmapplyconf -v -C /etc/cmcluster/dbcluster.config
4. Run the following command to start the cluster:
cmruncl
After the cluster is started, you can run the cmviewcl command to view the site configuration.
Configuring the Cluster File System Multi-node Package (SMNP)
If Cluster File System (CFS) is configured in the environment, the Serviceguard CFS (SG CFS)
package must be configured. To create an SG CFS SMNP package (SG-CFS-pkg), run the
cfscluster command. After creating the package, ensure that there are two CFS sub-clusters
in the Metrocluster.
Run the following command on any node, at both sites, to view the list of nodes and the status of
each node:
cfscluster status
Following is the output that is displayed:
Node : SFO_1
Cluster Manager : up
CVM state : up (MASTER)
Node : SFO_2
Cluster Manager : up
CVM state : up
