1) Shutdown all nodes  
2) Install and configure sg plugin on every node  
3) Start all nodes and wait until cluster state is yellow or green  
4) Run sgadmin

As soon as i install the plugin, I can't run the sgadmin.sh script because the nodes lose connectivity to each other. What is the correct order to configure all 3 nodes with the plugin?
