It'd be helpful to see the exact error message. I wrote this up after hitting 
some problems myself, might be worth reviewing:

I just noticed your comment on node 2 asking for a password. Maybe your ssh 
setup is not correct on that server. You might want to review it, you shouldn't 
get prompted for a password.

Are you using role separation (different users for GI and Database)?
Please post the output (exactly, just copy/paste) of the following commands:

node1$ id
node1$ ssh node1 date
node1$ ssh node2 date


node2$ id
node2$ ssh node1 date
node2$ ssh node2 date


Then repeat the command that doesn't work as expected (the command that 
receives the password prompt) with -v:

ssh -v node2 date
