How to properly shut down OpenBSD?

[rain1]

Hello

what is the best way to shut down an openbsd computer?

I have been doing su to get root and then shutdown -h. It doesn't fully shut down though, it mostly does but stops at "you computer has stopped. press any key to reboot.".

I have to hold the power button after that to get it to actually go off.

Is there an option i have to change of a different way to shut down the system?

See the -p option in the shutdown(8) manual page

My turn to say, "Hello, and welcome!"

The shutdown(8) program will call halt(8) after sending messages to all users at a specified time. If you do not need to inform other users or need to schedule shutdown for a specific time, you may use halt(8) directly.

Both shutdown(8) and halt(8) have a -p option. If the hardware supports automatic power down, the system will power off after the halt(8) completes. See either command's man page.

Right with a recent OpenBSD version.
But a not so long time ago, it was a different story.

I think "halt -p" works directly since OpenBSD 5.6 (not really sure it was 5.6...).
Before, you had to edit first /etc/rc.shutdown and change the powerdown value "powerdown=NO" in "powerdown=YES".

My user name is: open
My hostname is: r2d2

Using doas(1):

# grep halt /etc/doas.conf  
permit nopass open as root cmd /sbin/halt args -p
$ doas /sbin/halt -p

Using sudo from ports/packages:

# grep halt /etc/sudoers                                                       
open    r2d2=(root) NOPASSWD: /sbin/halt -p
$ sudo halt -p

You probably can make aliases in yours shell config to shorten that.

Thank you so much everyone, I will try it.

You could also try this:
$ doas sysctl hw.allowpowerdown=1

Then:
$ doas halt -p

If your system powers-down nicely, then make it permanent by adding the following line to /etc/sysctl.conf:

hw.allowpowerdown=1

Apologies for the 'necro-thread' post, but

shutdown -p now

worked perfectly for my [new]OpenBSD 6.4 install.

Interestingly enough, after installing OpenBSD-6.4, shutdown -p now no longer works. hw.allowpowerdown is set to 1. It's a minor issue to me (on a multiboot laptop and not tested on multiple installs) and I suspect it's just one of those oddities.

At some point, I'll install in a few more places and see if it's just on this laptop, an old L420 Thinkpad, that also has to have acpi disbabled before it will boot.
