Building an HA Cluster Configuration
Configuring the Cluster
Chapter 5 241
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 256. 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 from
Symantec” on page 29.
Verifying the Cluster Configuration
If you have edited a 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
The following items are checked:
• 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.
• Existence and permission of scripts specified in the command line.
• If all nodes specified are in the same heartbeat subnet.
• If you specify the wrong configuration filename.
• If all nodes can be accessed.
• No more than one CLUSTER_NAME, HEARTBEAT_INTERVAL, and
AUTO_START_TIMEOUT are specified.
• The value for package run and halt script timeouts is less than 4294
seconds.
•The value for NODE_TIMEOUT is at least twice the value of
HEARTBEAT_INTERVAL.
•The value for AUTO_START_TIMEOUT variables is >=0.
