UTM fails to power off after shutdown or gets stuck

Mateusz Bender

We have a small SG 115 UTM device at the office. We also have a UPS at the office which keeps the few servers we have running long enough for them to perform a graceful shutdown. In theory, I want the UTM to perform a graceful shutdown as well, but I'm having some issues with this.

A simple command is sent to the UTM via PUTTY: shutdown now

The command is clearly received by the UTM as the process is initiated. However, the UTM never really powers down. Well, if I connect a screen to the UTM, I get the following (terribly sorry for the poor quality): https://imgur.com/HTOT4Me

The last lines seem to read as follows:

Stopping Logging | done
Master Resource Control: runlevel 1 has been
Skipping services in runlevel 1: | utm-??? (I honestly can't make it out from the photo; yes, I know it's bad)

Additionally, looking into the system log, this is all I could find that seemed to be related to the actual shutdown:

What could be going on? I don't know if the UTM is safe to power off at this state or not - I'd prefer it to power off completely automatically. I haven't tried a manual reboot yet (will do so tomorrow, when I'm at the office), but I do know that the UTM has no trouble rebooting when installing updates.

    Found the reason, by testing the UTM on a VM (so that I could play around with the commands as much as I please without impacting the office).

    It seems the shutdown command doesn't, in fact, turn the system off at the end. Event with the -P parameter the end result is just as I described above. Instead it seems better to just use the halt command. This one works "as advertised". If someone wants to use shutdown to power off, then the additional -h flag is required (for some reason -P does nothing).
