Red Hat Summit4.5.3. Disabling ACPI completely in the GRUB 2 file
You can disable ACPI Soft-Off by appending acpi=off to the GRUB menu entry for a kernel.

This method completely disables ACPI; some computers do not boot correctly if ACPI is completely disabled. Use this method only if the other methods are not effective for your cluster.
Procedure
Use the
--argsoption in combination with the--update-kerneloption of thegrubbytool to change thegrub.cfgfile of each cluster node as follows:# grubby --args=acpi=off --update-kernel=ALL- Reboot the node.
Verification
- Verify that the node turns off immediately when fenced. For information about testing a fence device, see Testing a fence device
