Failover Clustering Error

Hi Experts,

We are asking for your help regarding our problem on Failover Clustering. We are testing the off-site failover of our exchange environment, we disconnect all servers on the primary site to simulate the downtime but we forgot to disconnect one mailbox server on this site the issue was when we return all the mailbox server to the primary site the two MB Server cannot joined to cluster anymore. I tried to clean up the node by using cluster node /forcecleanup but still it cannot joined to cluster. Any idea on this?

Thanks,
LVL 1

Hello,

What error do you get? What version of Exchange? Did you run Stop-DatabaseAvailabilityGroup -identity <DAGName> -ActiveDirectorySite <Primary AD site> before you activated the mailbox server in the secondary site?
