configuring apcupsd to suspend all running VM and then shutdown the esxi 5.5 u1 host
###############################################################################################################
# these are instructions for automating the suspend and shutdown of esxi vm's and host in case of a
# power failure.
# works with apc smartups 750xl and esxi 5.5u1
###############################################################################################################
0# make a new VM and install Ubuntu-Server on it
1# install apcupsd
apt-get install apcupsd
2# configure /etc/apcupsd/apcupsd.conf
3# enable apcupsd
vim /etc/default/apcupsd
ISCONFIGURED=yes
4# restart apcupsd
sudo service apcupsd restart
-------------------------------------------------
5# enable ssh on esxi
configuration-tab - security profile - properties (right upper corner)
6# copy shutdown_esxi.sh on esxi into datastore e.g. "/vmfs/volumes/MyDataStore/scripts
7# make the file executable
chmod +x shutdown_esxi.sh
--------------------------------------------------
8# configure passwordless ssh access on esxi
make keys on ubuntu server (as root, because apcupsd runs under root)
sudo -s
ssh-keygen -t rsa -b 2048
copy key to esxi server
cat /root/.ssh/id.dsa.pub | ssh root@192.168.3.125 ‘cat >> /etc/ssh/keys-root/authorized_keys’
now automated login should work on ubuntu server
ssh root@192.168.3.125 (the first time it asks to store esxi's key in local database, answer with "yes")
---------------------------------------------------
9# configure apc-script to run remote script on esxi
copy "doshutdown" to /etc/apcupsd (you mustn't rename it, otherwise apcupsd won't run it automatically)
make it executable
chmod +x doshutdown
#10 restart apcupsd
sudo service apcupsd restart
---------------------------------------------------
#!/bin/sh
WALL=wall
# this script is triggered in case the power fails
echo "suspending all VMs on ESXI..." | ${WALL}
# configured ssh-automatic-access with keys
ssh root@192.168.3.125 "nohup /vmfs/volumes/MyDataStore/scripts/shutdown_esxi.sh > /dev/null 2>&1 &"
echo "finished shutting ESXI down..." | ${WALL}
# exit code 99 - apccontrol stops after this script, so no shutdown of this host. this is for testing purposes
# exit code 0 - apccontrol continues with shutdown after this script
exit 99
#/bin/sh

#copy this file somewhere to datastore

# looks which vm's are running, sends them into suspend, waits until suspending-process is finished, then powers off esxi
