Description Raul Mahiques 2017-11-27 10:55:36 UTC
Document URL:

Section Number and Name: 
5.12. Configuring ACPI For Use with Integrated Fence Devices

Describe the issue: 
This section recommends disabling ACPI soft-off on systemd rather than on the BIOS, this is not correct because if the system is hanged the fencing of the node won't happen. The correct way should be to disable it on the BIOS first if possible.

The preferred way to disable ACPI Soft-Off is to set HandlePowerKey=ignore in the /etc/systemd/logind.conf file and verify that the node node turns off immediately when fenced, as described in Section 5.12.1, “Disabling ACPI Soft-Off in the logind.conf file”. 

Suggestions for improvement: 
Change recommendation to disable on the BIOS rather than systemd.
