Managing Serviceguard 13th Edition, February 2007

Building an HA Cluster Configuration
Configuring the Cluster
Chapter 5 227
For more information, see “Access Roles” on page 192 and “Editing
Security Files” on page 189.
Adding Volume Groups
Add any LVM volume groups you have configured to the ASCII cluster
configuration file, with a separate VOLUME_GROUP parameter for each
cluster-aware volume group that will be used in the cluster. These
volume groups will be initialized with the cluster ID when the
cmapplyconf command is used. In addition, you should add the
appropriate volume group, logical volume and filesystem information to
each package control script that activates a volume group. This process is
described in Chapter 6.
NOTE If you are using CVM disk groups, they should be configured after cluster
configuration is done, using the procedures described in “Creating the
Storage Infrastructure and Filesystems with VERITAS Cluster Volume
Manager (CVM)” on page 243. VERITAS disk groups are added to the
package configuration file, as described in Chapter 6.CVM is not
supported on all systems; see “About VERITAS CFS and CVM” on
page 27.
Verifying the Cluster Configuration
In Serviceguard Manager, click the Check button to verify the
configuration.
If you have edited an ASCII cluster configuration file using the command
line, use the following command to verify the content of the file:
# cmcheckconf -k -v -C /etc/cmcluster/clust1.config
Both methods check the following:
• Network addresses and connections.
• Cluster lock connectivity (if you are configuring a lock disk).
• Validity of configuration parameters for the cluster and packages.
• Uniqueness of names.
