Conﬁguring HP DCE Cells

Integrating DCE Services with MC/ServiceGuard

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 -a -i package_IP SUBNET

8. Halt the ServiceGuard cluster with the following command:

cmhaltcl -f

Conﬁguring the Package

Create a package for the DCE services that ServiceGuard can monitor

with the following steps:

1. Create a directory for the DCE package name as follows:

mkdir /etc/cmcluster/pkg-name.conf

2. Generate and modify the package conﬁguration script for DCE as

follows:

cmmakepkg -p /etc/cmcluster/pkg-name/pkg-name.conf

This command creates a template for pkg-name.

3. Edit this template for the DCE package by supplying the necessary

information (for example: PACKAGE_NAME, NODE_NAME). Use

the sample ﬁle dcepkg.conf for reference.
