7.2. Fence Device Components to Configure


This procedure consists of the following steps:
  1. The procedure configures two APC switches as fence devices that will be used as the main fencing method for each node in cluster backupclust.
  2. The procedure configures the main and backup fencing methods for clusternode1.example.com, using the two APC switches for the main fencing method for the node and using its IPMI management board as the backup fencing method for the node.
  3. The procedure configures the main and backup fencing methods for clusternode2.example.com, using the two APC switches for the main fencing method for the node and using its IPMI management board as the backup fencing method for the node.
  4. The procedure configures the main and backup fencing methods for clusternode3.example.com, using the two APC switches for the main fencing method for the node and using its IPMI management board as the backup fencing method for the node.
Table 7.4, “Fence Device Components to Configure for APC Fence Device” summarizes the components of the APC fence devices that this procedure configures for the nodes in the cluster backupclust.
