Configuring HP DCE Cells

Integrating DCE Services with MC/ServiceGuard

DCE Configuration for Integration with ServiceGuard

DCE configuration for integration with ServiceGuard is performed in the following steps:

1.Configuring the ServiceGuard cluster

2.Configuring DCE

3.Configuring the package

4.Distributing the package

5.Starting the ServiceGuard cluster

6.Starting the package on the ServiceGuard cluster

The following subsections describe these steps in more detail.

Configuring the ServiceGuard Cluster

Before configuring DCE for integration with ServiceGuard, you must install ServiceGuard. Then, install the DCE software on the primary and secondary nodes separately.

1.To configure the primary and secondary nodes in a ServiceGuard cluster, enter the following command:

cmquerycl -v -C /etc/cmcluster/cmclconfig.ascii \ -n primary_node -n secondary_node1 \

-nsecondary_node2

This command creates the template script /etc/cmcluster/cmclconf.ascii. Modify the script parameters to reflect your desired configuration, after which, the script seldom needs modification.

2.To determine if ServiceGuard daemons are running so that the DCE initial configuration program (dce_config) detects the presence of ServiceGuard enter the following command:

cmruncl -v-nprimary_node -nsecondary_node

3.Identify the hostname and IP address to be dedicated to the packages. To manually add the IP address to the cluster's primary node, enter the following command

cmmodnet -a-ipackage_IP SUBNET
