Chapter 3. Configuring IPMI Management Boards as Fencing Devices

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.

configuration file before and after the procedures documented in Section 3.3, “IPMI Fence Device

Configuration Procedure” and were performed.

Before the cluster resources and service were configured, the cluster.conf file appeared as

follows.
