Under Cluster > Cluster Management ..there is an option to shutdown cluster

If you want to automate this, then you would most likely want to do this via a script so that you don't need human interaction.  I would recommend setting up a SSH key pair between a machine that notices that power is on UPS and the cluster.  For additional security, I would recommend setting up sudo on the cluster.  But a short shell script that will do this follows:

cat << EOF | /usr/bin/isi config

shutdown all

yes

EOF

I would rather be notified of UPS failure and manually initiate this shutdown process, imagine an RCA explaining a bug in the script that took everything offline. Oopss ☺

Agreed.  Just providing a method.  However if you know your UPS battery is going to die in 10 minutes, I would rather have a graceful shutdown than a hard down.  Everyone has different needs.
