Hi All,

I have tested Shield on single node, now i want implement shield in production environment where we are having 3 node cluster.

Do i need to stop all nodes and implement shield or can i go with one node after another by keeping production environment alive?

It needs to be installed on all of them at the same time, so you will need to shut them down.
