Hi Frnds... I have Installed an Exchange 2007 CCR Cluster on Windows 2008 SP2. But i am Facing some Problem in My Cluster. When i am Moving The Ownership From Node-1 to Node-2 My First Storage Group (MailBox Store) Goes in Offline when i am Moving My Cluster From Node-2 To Node-1 It Works Fine. So is there any Solutions To Solve This issue. Thanks in Advance Mahipal Jhala

Hi, Can you post some logs from the eventviewer? Did you try to failover with the PowerShell command? Does it work than? Cause its not the intention to start failovering from you cluster console. Here is the PS command. Move-ClusteredMailboxServer –Identity:E2K7MBX –targetmachine:Node-2 Change the "node name" to failover to the previous state... Let me know if this goes without problems. Between failovers give the exchange some time to start replicating again... Greetzz, Timmy

Hi, This looks all normal. This is concerning the search indexer. But thats normal when a db shutsdown. Is this on the active node at time of failover? I don't know what is wrong here... Everything shutsdown normal. And the other node? Greetzz, Timmy

Hi I have tried on Power Shell but no success. it gives below erre. Move-ClusteredMailboxServer : Continuous replication is in a failed, seeding, o r suspended state on 'First Storage Group'. Move-ClusteredMailboxServer cannot be performed if one or more of the server's storage group copies are in failed, seeding or suspended states. At line:1 char:28 + Move-ClusteredMailboxServer <<<< -Identity:E2K7MBX -targetmachine:E2K7MBXN02 Regards, Mahipal Jhala
