Configuring HP DCE Cells
Integrating DCE Services with MC/ServiceGuard
Configuring DCE
Perform the following steps to configure DCE on your system if the ServiceGuard is running:
1.Create a volume group for the DCE data file (for example : /dev/vgdce).
2.Manually activate the volume group to be accessed from the primary node (for example: vgchange
3.Identify the filesystems and logical volumes for the package filesystem definition. These should reside in the shared disk.
For most installations, HP recommends that the three directory trees /krb5, /var/opt/dce, and /etc/opt/dce be set up as logical volumes after the DCE software has been installed, but before DCE has been configured on the ServiceGuard cluster.
Before running the DCE initial configuration program, manually mount these logical volumes on shared disk to be accessed from the primary node.
4.Once dce_config is invoked, it asks if the DCE Core services will be run under a ServiceGuard package. Answer yes. Then dce_config prompts for a “package hostname.” Enter the package hostname. From this point on, the dce_config script proceeds normally.
5.When the DCE configuration procedure is complete, the daemons for the core services are automatically started. Use dce_config to manually shutdown the DCE services that are running standalone.
6.Unmount and deactivate the volume group, which is in the shared disk.
7.Manually remove the IP address from the cluster with the following command:
cmmodnet
8. Halt the ServiceGuard cluster with the following command:
cmhaltcl
