You will need to eject a node from the DAG, as a three server cluster is a majority node set and will not use the witness server.

We have a 3 node DAG consisting of 2 mailbox servers (exch001, exch002) and 1 CAS/HUB/MB server (exch003). The thought was to only recover the CAS/HUB/MB server and as long as the witness server was available we should be fine. We got the server to come up, and all of the Exchange services are running, but I can't activate the mailbox. It complains that it can't see the server that held the active database. I tried activating using the EMC and by using: Move-ActiveMailboxDatabase -Identity "MAILBOXDB" -ActivateOnServer "EXCH003" -MountDialOverride "None" -SkipActiveCopyChecks and end up with Active Manager isn't reachable on server exch001.scvl.com. The Microsoft Exchange Replication service might not be running. Error Error 0x6ba (The RPC server is unavailable) from cli_GetPrimaryActiveManager. + CatagoryInfo : InvalidOperation (HQMBDB:ADObjectId) + [Move-ActiveMailboxDatabase], InvalidOperationException + FullyQualifiedErrorId : + 7862D273.Microsoft.Exchange.Management.SystemConfigurationTasks.MoveAc + tiveMailbox.Database eseutil /g tells me that the database is okay. EMC tells me that the active status is false and the copy status is failed (of course). Is there a way to activate a database on a single server without it looking for the other members of the DAG? -Paul --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
