4.3. IPMI Fence Device Configuration Procedure

This section provides the procedure for adding an IPMI fence device to each node of cluster ipmiclust. Each node of ipmiclust is managed by its own IPMI management board.
Use the following procedure to configure the IPMI management board as the fence device for node clusternode1.example.com using Conga:
  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 ipmiclust displayed, along with the nodes that make up the cluster. Click on clusternode1.example.com. This displays the configuration screen for node clusternode1.example.com.
  3. At the Main Fencing Method display, click Add a fence device to this level. This causes a dropdown manu to display.
  4. From the dropdown menu, under Create a new Fence Device, select IPMI Lan. This displays a fence device configuration menu, as shown in Figure 4.2, “Creating an IPMI Fence Device”.

  5. For Name, enter ipmifence1.
  6. For IP Address, enter 10.15.86.96.
  7. For Login, enter ipmilogin.
  8. For Password, enter ipmipword.
  9. For Password Script, leave the field blank.
  10. For Authentication type, enterpassword. This field specifies the IPMI authentication type. Possible values for this field are none, password, md2, or md5.
  11. Leave the Use Lanplus field blank. You would check this field if your fence device is a Lanplus-capable interface such as iLO2.
  12. Click Update main fence properties. This causes a confirmation screen to be displayed.
  13. On the confirmation screen, click OK. After the fence device has been added, a progress page is displayed after which the display returns to the configuration page for clusternode1.example.com in cluster ipmiclust.
After configuring an IPMI fence device for clusternode1.example.com, use the following procedure to configure an IPMI fence device for clusternode2.example.com.
  1. From the configuration page for clusternode1.example.com, a menu appears on the left of the screen for cluster ipmiclust. Select the node clusternode2.example.com. The configuration page for clusternode2.example.com appears, with no fence device configured.
  2. At the Main Fencing Method display, click Add a fence device to this level. This causes a dropdown manu to display.
  3. From the dropdown menu, under Create a new Fence Device, select IPMI Lan. This displays a fence device configuration menu.
  4. For Name, enter ipmifence2.
  5. For IP Address, enter 10.15.86.97.
  6. For Login, enter ipmilogin.
  7. For Password, enter ipmipword.
  8. For Password Script, leave the field blank.
  9. For Authentication type, enterpassword. This field specifies the IPMI authentication type. Possible values for this field are none, password, md2, or md5.
  10. Leave the Use Lanplus field blank.
  11. Click Update main fence properties. This causes a confirmation screen to be displayed.
  12. On the confirmation screen, click OK. After the fence device has been added, a progress page is displayed after which the display returns to the configuration page for clusternode1.example.com in cluster ipmiclust.
After configuring ipmifence2 as the fencing device for clusternode2.example.com, select node clusternode3.example.com from the menu on the left side of the page and configure an IPMI fence device for that node using the same procedure as you did to configure the fence devices for clusternode2.example.com and clusternode3.example.com. For clusternode3.example.com , use ipmifence3 as the name of the fencing method and 10.15.86.98 as the IP address. Otherwise, use the same values for the fence device parameters.
