3.5. Configuring Fence Devices

Configuring fence devices consists of creating, modifying, and deleting fence devices. Creating a fence device consists of selecting a fence device type and entering parameters for that fence device (for example, name, IP address, login, and password). Modifying a fence device consists of selecting an existing fence device and changing parameters for that fence device. Deleting a fence device consists of selecting an existing fence device and deleting it.


If you are creating a new cluster, you can create fence devices when you configure cluster nodes. Refer to Section 3.6, “Configuring Cluster Members”.
With Conga you can create shared and non-shared fence devices.
The following shared fence devices are available:
  • APC Power Switch
  • Brocade Fabric Switch
  • Bull PAP
  • Egenera SAN Controller
  • GNBD
  • IBM Blade Center
  • McData SAN Switch
  • QLogic SANbox2
  • SCSI Fencing
  • Virtual Machine Fencing
  • Vixel SAN Switch
  • WTI Power Switch
The following non-shared fence devices are available:
  • Dell DRAC
  • HP iLO
  • RPS10 Serial Switch
This section provides procedures for the following tasks:
The starting point of each procedure is at the cluster-specific page that you navigate to from Choose a cluster to administer displayed on the cluster tab.

3.5.1. Creating a Shared Fence Device

To create a shared fence device, follow these steps:
  1. At the detailed menu for the cluster (below the clusters menu), click Shared Fence Devices. Clicking Shared Fence Devices causes the display of the fence devices for a cluster and causes the display of menu items for fence device configuration: Add a Fence Device and Configure a Fence Device.


    If this is an initial cluster configuration, no fence devices have been created, and therefore none are displayed.
  2. Click Add a Fence Device. Clicking Add a Fence Device causes the Add a Sharable Fence Device page to be displayed (refer to Figure 3.1, “Fence Device Configuration”).

  3. At the Add a Sharable Fence Device page, click the drop-down box under Fencing Type and select the type of fence device to configure.
  4. Specify the information in the Fencing Type dialog box according to the type of fence device. Refer to Appendix B, Fence Device Parameters for more information about fence device parameters.
  5. Click Add this shared fence device.
  6. Clicking Add this shared fence device causes a progress page to be displayed temporarily. After the fence device has been added, the detailed cluster properties menu is updated with the fence device under Configure a Fence Device.
