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 \
-n secondary_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 -n primary_node -n secondary_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 -i package_IP SUBNET
