2.3.2. Disabling ACPI Soft-Off with the BIOS
The preferred method of disabling ACPI Soft-Off is with
chkconfig management (Section 2.3.1, “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:
- Reboot the node and start the
BIOS CMOS Setup Utilityprogram. - Navigate to the menu (or equivalent power management menu).
- At the menu, set the function (or equivalent) to (or the equivalent setting that turns off the node via the power button without delay). Example 2.11, “
BIOS CMOS Setup Utility: set to ” shows a menu with set to and set to .Note
The equivalents to , , and may vary among computers. However, the objective of this procedure is to configure the BIOS so that the computer is turned off via the power button without delay. - Exit the
BIOS CMOS Setup Utilityprogram, saving the BIOS configuration. - When the cluster is configured and running, verify that the node turns off immediately when fenced.
Note
You can fence the node with thefence_nodecommand or Conga.
