2. Reboot the node.

3. When the cluster is configured and running, verify that the node turns off immediately when

fenced.

Tip

You can fence the node with the fence_node command or Conga.

3.2. Disabling ACPI Soft-Off with the BIOS

The preferred method of disabling ACPI Soft-Off is with chkconfig management (Section 3.1,

“Disabling ACPI Soft-Off with chkconfig Management”). However, if the preferred method is

not effective for your cluster, follow the procedure in this section.

Note

Disabling ACPI Soft-Off with the BIOS may not be possible with some

computers.

You can disable ACPI Soft-Off by configuring the BIOS of each cluster node as follows:

1. Reboot the node and start the BIOS CMOS Setup Utility program.

2. Navigate to the Power menu (or equivalent power management menu).

3. At the Power menu, set the Soft-Off by PWR-BTTN function (or equivalent) to Instant-Off

(or the equivalent setting that turns off the node via the power button without delay).

Example 2.10, “BIOS CMOS Setup Utility: Soft-Off by PWR-BTTN set to Instant-Off”

shows a Power menu with ACPI Function set to Enabled and Soft-Off by PWR-BTTN set

to Instant-Off.
