[Apcupsd-users] doshutdown script problems

[Matthew T. K. <mat...@gm...>]

Hey all,

I have googled this issue, and came across users back in 2012 having the
same issue, but there was never a solution posted.

My issue is as follows:

Apcupsd (3.14.10 from Ubuntu repositories) is running on Ubuntu Server
14.04 as a guest in ESXi using an APC SUA1500 UPS.

Instead of shutting down the guest when power has run low, I need it to
send a command to the ESXi host, to shut down all guests and power off.

In order to accomplish this, I created a mini doshutdown script and placed
it in /etc/apcupsd as instructed in the manual.

It looks like this:

__________________________

#!/bin/sh
plink -ssh -2 -pw password ro...@xx... "/sbin/shutdown.sh &&
/sbin/poweroff"
exit 99
__________________________


Plink is a simple command that sends an ssh command to a remote host, in
this case the ESXi host.


The /etc/apcupsd folder looks as follows:
__________________________

# ls -lh

-rwxr-xr-x 1 root root 3.9K Oct 20 19:28 apccontrol
-rw-r--r-- 1 root root  13K Oct  5 21:31 apcupsd.conf

-rw-r--r-- 1 root root    0 Oct 21 13:24 powerfail
-rwxr-xr-x 1 root root  944 May 19  2013 ups-monitor
__________________________

If I log in as root, go to the /etc/apcupsd folder and execute ./doshutdown
everything works as expected, each guest on the ESXi server (including the
ubuntu server 14.04 guest running apcupsd) goes through an orderly
shutdown, followed by the host shutting down.

Good thus far.

Now however, if I power everything back up again, and instead unplug the
UPS I get the following:

__________________________

Broadcast Message from root@apcupsd

        (somewhere) at 12:39 ...



Power failure on UPS SUA1500. Running on batteries.
__________________________

followed (~45 minutes later) by:

__________________________
Broadcast Message from root@apcupsd

        (somewhere) at 13:24 ...



Remaining battery runtime below limit on UPS SUA1500. Doing shutdown.





Broadcast Message from root@apcupsd

        (somewhere) at 13:25 ...



Continuing with shutdown.
__________________________

but neither the host, nor the guest shut down.

The script appears to be of the correct name, and to be in the correct
location.

apcupsd even seems to detect that it is exiting with 99, as it skips the
default shutdown activity.   It just never seems to execute my plink
command.


What's worse, in my test, it still sends the killpower command to the UPS,
so after the preset delay (9 minutes in my case) the UPS cut power to the
still running host.  (luckily nothing broke)

Has anyone else run into this problem before?  Were you able to solve it?
How?

Thank you very much,
Matt
