[gentoo-user] apcupsd to recycle power

[gentoo-user] apcupsd to recycle power

[Thanasis]

I have an APC SC620I, which in case of power failure, it successfully 
initiates a shutdown to the connected (via SMART cable) PC, but if the 
mains power returns, the UPS does not recycle the power to the PC, and 
consequently the PC stays off.

Regardless if the mains power returns soon after the UPS has initiated a 
shutdown to the PC, shouldn't the UPS recycle the power anyway, so that 
the PC comes back on as set in BIOS?

Am I missing something in the configuration or the daemons that should
be running?

I'm afraid I don't have an APC UPS to know its quirks, but in my case I have 
these running:

upsd
upsdrv
upslog
upsmon


Is it that the UPS does not recycle the power, or is it that the PC does not 
reboot after power is restored?  Does the PC reboot if you pull and reinsert 
its mains plug?

WARNING:  don't just pull the plug in a fully working system to avoid fs

correctly it should reboot as soon as you reconnect the mains supply to it.

The UPS does NOT recycle the power.

The PC's BIOS is correctly configured and tested to start up as soon as 
power is restored to it.

Looks like the UPS does not cut (kill) the power, but I am not sure how 
to debug it.

If the UPS battery has not run flat before the mains power is restored, 
I see no reason why a UPS should kill the output power. So the BIOS has 
no real way of knowing that it should reboot again in that case.

Have you looked for any BIOS options related to powering on from a USB 
device? eg, I'm thinking of PCs which can be switched on by pressing a 
key on the keyboard... could that mechanism be triggered by a UPS? Or 
perhaps via wake-on-lan? (Note I have no real experience with UPSs, I'm 
just trying to think of other ways that PCs can be made to power on).

The PC has an option in BIOS to "Power On" when the mains power is 
restored to it, without any need to press any button.
So, once the UPS has initiated a shutdown to the PC, the PC will 
shutdown, and if the mains power is restored (to the UPS) shortly after 
the PC has shutdown, how will the UPS make the PC come back on, unless 
it cuts (kills) the power to PC's cord, and then restores it after a few 
seconds.

On the same page it lists a number of tests you can perform:

http://www.apcupsd.com/manual/manual.html#testing-apcupsd

Have you been through them and in particular the "Full Power Down Test"?  If 
yes, did you wait long enough after the PC has powered down, for the UPS to 
also switch off (you can affect the overall waiting time by setting a shorter 
TIMEOUT value, rather than waiting for the batteries to go flat). 

If this does not get you somewhere, I recommend you post to the  
nut-upsuser@lists.alioth.debian.org (you'll need to register first).  The 
developers and contributors are offering friendly advice and are very 
knowledgeable on all things UPS related, including annoying bugs with firmware 
that defeat reason.

PS. The services I listed running are particular to my UPS, I expect different 
to your APC unit.

Yes I have set the TIMEOUT to 30 (seconds) in /etc/apcupsd/apcupsd.conf, 
and run the tests. Waited more than 3 minutes after the PC powers off, 
the UPS will not kill the power.

Is the above list (nut-upsuser@lists.alioth.debian.org) also appropriate 
for apcupsd users?

Yes, because they belong to sys-power/nut. I 've been talking about 
sys-power/apcupsd, as I said in first post.

I'm sure I saw threads there on APC UPS, so yes it won't hurt if you post 
there.

You can try sys-power/nut, and use something like:

sudo /opt/local/bin/usbhid-ups -a apcups -DD

to get some debug info from your UPS, after you set up the configuration 
files.  You could either try the apcupsd-ups driver which acts as an apcupsd 
client, or you give usbhid-ups a spin as I show above.  In any case, I trust 
that the guys at the nut M/L will give sound advice for your particular UPS - 
unless some gentoo user with this UPS chimes in first.

HTH.

Obviously not directly applicable, but I use nut and a cyberpower UPS
and the shutdown scheme it employs is that the master (controls the
UPS) commands everything else to shut down, then it begins shutdown,
and just before powering off it sends a command to the UPS which
causes a several second delay followed by a power off, and then it
powers off the host (which is otherwise shutdown already).

I need to re-read how exactly this is implemented.

As I wrote in the initial post I am running apcupsd because my UPS is an

I assume that your PC shuts off thus reducing the load - and, of course,
this increases the runtime of the remaining battery so the UPS never
actually shuts down?

I don't think you can get apcupsd in any case to cycle the outlet
groups, but you can try a couple things.

First, is apcupsd even sending the signal to shutdown the UPS?

/etc/init.d/apcupsd.powerfail needs to be added to the shutdown runlevel:

`rc-update add apcupsd.powerfail shutdown`

At the end of the shutdown this is run and it tells the UPS to power
off. If you have multiple PCs this should be enabled on the slowest to
shutdown to make sure it doesn't kill a machine still shutting down.

If the above fails (if the above does indeed fail, some troubleshooting
should happen to try to figure out why it doesn't work), KILLDELAY is
the parameter you likely seek, but it is dangerous. If you set this it
will wait x seconds after a shutdown was requested and forcibly shut
down the UPS power.

However, in the even that power is restored between the UPS kill and the
time it actually turns off the mains will still not be cycled. But
theoretically this window should be pretty small.

I have even tried to run the command "/sbin/apcupsd --killpower" from a 
root terminal (while in default runlevel, after manually creating the 
file /etc/apcupsd/powerfail) and nothing happened.

That was a musing, it wasn't based on testing. On most UPS systems I've
seen when the power comes back the UPS resets.

As I said, you can time your shutdown and set KILLDELAY, but make sure
you add some extra time in case the shutdown takes longer than expected.
`man apcupsd.conf` only has a two-sentence description for killdelay usage.

Are you sure you have "fully characterized the UPS behaviour? Often hardware
related to power says one thing in manuals and behave quite differently
in relality, particulary as the equipment ages and the firmware inside
is not upgraded.

A multi meter is an indspinabled piece of diagnosis equipment to actually
monitor the outlest  both feeding utility power to the UPS and the outlets
on the UPS. Furthermore not every port on the UPS acts the same. Start with
the manual, but *verify* base on conditions.

Another problem. Much of the software (firmware inside the ups) is bullshit.
There are not easy/reliable methods to tell exactly how much energy is
in a new battery at any given point it time. The problem is further
exasperated as batteries and circuit components age. Old UPSes act weird
the older the hardware gets. The sensor circuits and the heuristics/bullshit
math used to measure currently stored energy in a battery. If you doubt any
of this, go to any semiconductor site that has lots of technology for
batteries and you'll be astonished at the voodoo
that is the basis of those algorithms.

So not that you understand that limitation of physcis (currrent EE 
technology) it's easy to understand why you must verify (characterize)
performance.  Do change the UPS batteries, if they are older than 3 years
(2 years if they are cheap no name brand, not Mil spec) type of crap.
All batteries are crap; but there is much more to these systems I am
not going into.

UPdate your ups firmware, often: (from the apc site).

http://www.apc.com/search-apc/us/en/relevance/10_1/Product
Information;;7B0CB5EA-CEC6-4E31-B9A6-51E4DCFADB54/all?search_text=upgrade
firmware&search_type=new&filters=

Monitor the actual voltage level on the output port of the ups where
your PC is plugged in.  Use common sense about electricty.

If the ups software is dysfuntional, then find a solution that avoids it.

For example, WOL Wake on Lan:

https://wiki.archlinux.org/index.php/Wake-on-LAN

Once again Arch kicks gentoo in the teeth with excellent documents. ymmv.

Research WOL, etherboot and any other way that another system can
send a signal over ethernet to you PC to boot up. Sometimes I run
that over a serial port embedded device to the pc, as an embedded
system can last years or decades on a (solar) battery system, if you
auto reboot is really critical.


Also look at the patents held by Peter Pulizzi. Pretty much the "shit"
when it comes to remote power control:

http://patents.justia.com/inventor/peter-s-pulizzi

Software is nothing without motivated Electrical Engineeers.
(Respect your elders because they have paved a path forward for you).


Now, get real. Get my bud, meino to whip together a $20 micro and a relay
with a control port into a metal box, (code) so you can build your
own reboot box!

What he'll charge you?  

Or keep working with software built ontop of "crap assumptions". After
a while you'll "get it".

Or buy a UPS with know proven functionality?


Naw, just be a "hack" and cludge something "admin_ish" together?

Those cheap UPS codes are crap. All of them. If you are motivated,
most can be "downloaded" and picked apart, if you are motivated.

it does seem as though this hits the issue - that when power fails, the 
ups triggers a shutdown, but the power doesn't fail hard enough to wind 
down the ups too, in which case the machine that is waiting for the 
"offbattery" event is fast asleep and misses the message. it's a shame 
the killpower command does nothing for you.

the only way forward that i see would be to get a small device a la 
raspberry pi, and have that run apcupsd on it.  you can then have that 
device run wake on lan if it detects the power is good, and trigger 
remote shutdown when not.

Thanks.
I am going to try and do some more tests though ...

Not all UPSs have functionality to cycle the power outputs when the power 
returns.
And some that do require a specific command to be sent to it to enable this, 
which might need some closed-source client that only works on MS Windows.

A few years ago there was a message on the nut website asking for a boycot of 
APC because they changed the protocol and refuse to provide info on it, 
forcing people to use the APC bloatware. (Requiring Java just to talk to a 
UPS?)
