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
