6.2. Fence Device Components to Configure

This procedure configures two APC switches as fence devices that will be used for each node in cluster apcclust. Then the procedure configures both of those switches as part of one fencing method for clusternode1.example.com, clusternode2.example.com, and clusternode1.example.com.
Table 6.3, “Fence Device Components to Configure for APC Fence Device” summarizes the components of the APC fence devices that this procedure configures for cluster node clusternode1.example.com.

Table 6.3. Fence Device Components to Configure for APC Fence Device

Fence Device Component Value Description
Fencing Type APC Power Switch type of fencing device to configure for each APC switch
Name pwr01 name of the first APC fencing device for node1.example.com, node2.example.com, and node3.example.com
IP address 10.15.86.96 IP address of the first APC switch to configure as a fence device for node1.example.com, node2.example.com, and node3.example.com
Name pwr02 name of the second APC fencing device for node1.example.com, node2.example.com, and node3.example.com
IP address 10.15.86.97 IP address of the second APC switch to configure as a fence device for node1.example.com, node2.example.com, and node3.example.com
login apclogin login value for the each of the APC switches that control the power for for clusternode1.example.com, clusternode2.example.com, and clusternode3.example.com
password apcpword password for each of the APC switches that control the power for for clusternode1.example.com, clusternode2.example.com, and clusternode3.example.com
Table 6.4, “Fence Agent Components to Specify for Each Node in apcclust ” summarizes the components of each of the APC fence devices that you must specify for the cluster nodes in apcclust.

Table 6.4. Fence Agent Components to Specify for Each Node in apcclust

Fence Agent Component Value Description
fence device pwr01 name of the first APC fence device you defined as a shared device
fence device pwr02 name of the second APC fence device you defined as a shared device
port 1 port number on each of the APC switches for node1.example.com
port 2 port number on each of the APC switches for node2.example.com
port 3 port number on each of the APC switches for node3.example.com
The remainder of the fence device components that you configure for each fence device for each node appear automatically when you specify that you will be configuring the pwr01 or pwr02 fence device that you previously defined as a shared fence device.
