FreePBX Hot Spare Configuration Question

Hello I have followed the FreePBX help topic from within the wiki,

http://wiki.freepbx.org/display/FPG/Warm+Spare+Setup.

In this scenario there is a primary server and a hot spare server …

Primary Server —> Hot Spare Server 1

.
I would like it to be like this …

I have no idea how to accomplish the SSH Keys from one Primary and 2 Hot Spares. I can get the Primary and the first Hot spare’s SSH keys to work without issue. When I try the third server however I keep getting that the keys were already generated and do I want to delete and recreate which. I am thinking is going to break the relationship from the Primary and Hot Spare 1 server that I already hot gotten to work.

Any help?? Any direction would be greatly appreciated … Thanks!!
