1. I realize I have to copy /etc/pve/cluster.conf.new on all nodes
   My concern is name ipmi1 & ipmi2 where those name come from are those just generic name or is that something I have to look in my Supermicro Server under IPMI ? and same goes to fence_ipmilan …
   
   
   Also what exactly is
   <service autostart="1" exclusive="0" name="ha_test_ip" recovery="relocate">
   <ip address="192.168.7.180"/>
   </service>
   
   
   
   
   What is HA_TEST_IP and the IP .180 ? Thanks for the WIKI but its not very much clear as which line goes as I don't wanted to make sure it make sense before I start copy and paste as thats not always work.
   
   
   Thank you for your time.

1. I realize I have to copy /etc/pve/cluster.conf.new on all nodes

no. due to pmxcfs this is replicated automatically

Also what exactly is
<service autostart="1" exclusive="0" name="ha_test_ip" recovery="relocate">
<ip address="192.168.7.180"/>
</service>

This is just a test IP, can be used to test HA failover. Remove it if you do not want to use it.
