How do I create a copy of Exchange 2010 database via a Database Availability Group?
Posted on 2010-08-30
I recently installed Exchange 2010 Standard on two virtual servers running Windows Server 2008 R2 Enterprise and created a Database Availability Group (DAG). Under my Exchange Management Console, in Organization/Mailbox/Database Management, I see both Mailbox Databases listed. However, when I click on my primary mailbox database, I see only one database copy listed in the bottom window (with a copy status of Mounted). So I tried using EMS to do an Add-MailboxCopy which failed with:
(PID 5592, Thread 24) Task Add-MailboxDatabaseCopy writing error when processing record of index 0. Error: Microsoft.Exchange.Cluster.Replay.SeedInProgressException: A server-side seed operation has failed. Error: An error occurred while performing the seed operation, which may indicate a problem with the source disk. Error: An error occurred while attempting to access remote resources. Error: An error occurred while processing a request on server 'EXCHANGE2010'. Error: Database '68a9c054-b1a6-4e10-8df9-948869b045be' was not active on source server 'EXCHANGE2010'.
(Exchange2010 is my primary server’s name from whence this operation was done.) All services are active and except for this error appearing in the event log, no other errors are listed.
When I click on Add Mailbox Database Copy in EMC, it shows both my servers stating they already have a copy. But when I double click on that database, the properties show that Seeding is False and Never is given for “Latest available log time”, “Last inspected log time”, “Last copied log time”, and “Last replayed log time”. Therefore, it appears that there is no real copy or redundancy in place. Shouldn’t both servers participating in the replication be listed under the server’s database? And what should the Copy Status be listed as? (Healthy?) How do I get a copy created?
