3.4. Cluster Configuration File with APC Fence Device
Configuring a cluster with Conga modifies the cluster configuration file. This section shows the cluster configuration file before and after the procedures documented in Section 3.3, “APC Fence Device Configuration Procedure” were performed.
Before the cluster resources and service were configured, the
cluster.conf file appeared as follows.
