3.5.2. Disabling ACPI Soft-Off with the BIOS
The preferred method of disabling ACPI Soft-Off is with
chkconfig
management (節 3.5.1, “Disabling ACPI Soft-Off with chkconfig
Management”). However, if the preferred method is not effective for your cluster, follow the procedure in this section.
注意
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 Utility
program. - Navigate to the Power menu (or equivalent power management menu).
- 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). 範例 3.1, “
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.注意
The equivalents to ACPI Function, Soft-Off by PWR-BTTN, and Instant-Off 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 Utility
program, saving the BIOS configuration. - When the cluster is configured and running, verify that the node turns off immediately when fenced.
注意
You can fence the node with thefence_node
command or Conga.
