Note
You can test the fencing configuration manually with the fence_node command. Test early and
often.
3.3.4. Red Hat Cluster Suite services
There are now enough hardware and software pieces in place that the cluster.conf file can be
completed and parts of the cluster can be initialized. Red Hat Cluster Suite consists of a set of services
(cm an, qdisk, fenced) that ensure cluster integrity. The values below are from the RAC example, with
HA values in comments. The timeouts are good starting points for either configuration and comments
give the HA equivalent. More details on the RAC example will be provided in Chapter 4, RAC/GFS Cluster
Configuration. More details on the HA example will be provided in Chapter 5, Cold Failover Cluster
Configuration.

The cluster node names rac7-priv and rac8-priv need to be resolved and therefore are included
in all nodes' /etc/hosts file:
