Table 2.2. Fence Device Components to Configure for APC Fence Device
Table 2.3, “Fence Agent Components to Specify for Each Node in apcclust ” summarizes the
components of the APC fence device that you must specify for the cluster nodes in apcclust.
Fence Agent
Component
Value Description
fence device apcfence name of the APC fence device you defined as a shared device
port 1 port number on the APC switch for node1.example.com
port 2 port number on the APC switch for node2.example.com
port 3 port number on the APC switch for node3.example.com
Table 2.3. Fence Agent Components to Specify for Each Node in apcclust
The remainder of the fence device components that you configure for each node appear automatically
when you specify that you will be configured the apcfence fence device that you previously defined
as a shared fence device.
2.3. APC Fence Device Configuration Procedure
This section provides the procedure for adding an APC fence device to each node of cluster
apcclust. This example uses the same APC switch for each cluster node, which will first be
configured as a shared fence device. After configuring the APC switch as a shared fence device, the
device will be added as a fence device for each node in the cluster.
To configure an APC switch as a shared fence device using Conga, perform the following procedure:
1. As an administrator of luci Select the cluster tab. This displays the Choose a cluster to
administer screen.
2. From the Choose a cluster to administer screen, you should see the previously configured
cluster apcclust displayed, along with the nodes that make up the cluster. Click on apcclust to
select the cluster.
3. At the detailed menu for the cluster apcclust (below the clusters menu on the left side of the
screen), click Shared Fence Devices. Clicking Shared Fence Devices causes the display of any
shared fence devices previously configured for a cluster and causes the display of menu items for
fence device configuration: Add a Fence Device and Configure a Fence Device.
4. Click Add a Fence Device. Clicking Add a Fence Device causes the Add a Sharable Fence
Device page to be displayed.
