4 node SCC and SCR design problem   
Hi all, 

I have 4 node SCC cluster enabled ( 2 active and 2 passive nodes) and want 
to enable SCR copies to second site. Each Active EX server will have its own 
single node standby SCR target server. It will look like this: 

EX2007 SCC cluster: 

NODE1_A --NODE2_A---NODE3_P---NODE4_P 

NODE1_A -------SCR copy-------EXDRSRV1 
NODE2_A--------SCR copy-------EXDRSRV2 

When i enable SCR copies in the second site i know that it will work fine 
and that i can even activate each DR server. But i am concerned about 
activating the primary servers again ( theoreticaly when primary site comes 
back online). I must firs enable NODE1_A and NODE2_A as SCR targets. But will 
I be able to activate the targets since both servers are members of 4 node 
SCC cluster? I can activate one mailbox server but will i be able to activate 
the second mailbox server in the cluster since it says : " If the SCR target 
computer is a cluster node, the node must be a passive node (e.g., the 
passive clustered mailbox role is installed), and the cluster cannot contain 
any clustered mailbox servers. " 

If that's the truth, than SCR with SCC can only work in 2 node SCC scenario? 
Any comments? 

Thanks, 

Zuki
