Red Hat CLUSTER SUITE FOR ENTERPRISE LINUX 5.1 : Installation guide : Page 29

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 BIO S C MO S Setup Uti l i ty program.

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

3. At the Po wer menu, set the So f t - O f f b y PWR - BT T N function (or equivalent) to In st an t -

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

Example 2.1, “ BIO S C MO S Setup Uti l i ty: Soft-Off by PWR-BTTN set to Instant-Off”

shows a Po wer menu with ACPI Fu n ct io n set to En ab led and So f t - O f f b y PWR- B T T N

set to In st an t - O f f .

Note

The equivalents to AC PI Fun ct io n , So f t - O f f b y PWR - BT T N, and In st an t - O f f 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.

4. Exit the BIO S C MO S Setup Uti l i ty program, saving the BIOS configuration.

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

fenced.

Note

You can fence the node with the fence_no d e command or Co n g a.
