Exchange 2010 - How to change Primary Servers

Setup:
- 2 Locations
- 2 2010 Exchange Servers running on Windows Server 2008R2 Enterprise
- DAG is setup and Secondary server has a full replication of the databases.
- 1 Primary server needs to be taken offline to increase the raid size

How do I tell Exchange to treat the secondary exchange controller as the primary during this interlude?

I should note that both servers have all the roles. I am assuming I need to make the secondary server databases active. However, are there DNS settings that need to be changed? Will connectors still function properly?

If all you want to do is active the database copy on the other secondary server use the following command below..

Use the StartDagServerMaintenance.ps1 and StopDagServerMaintenance.ps1

See the follow link for more detail on the above powershell scripts.
Database Maintenance Mode Exchange 2010

You also need to make sure that your CAS server is also load balanced as well.

ok. Two questions:
1) I don't think load balancing was setup. What effect does this have?
2) Will mail continue to flow if the primary server is offline for the next 4-5 days?

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Question 1 - You need to have CAS load balanced and your CAS servers should be in a CAS Array  (1 CAS array for every AD site that host Exchange). Because you are using DAG and have all of the roles installed on both servers you need to use a hardware load balancer for Exchange CAS role. WNLB is not supported in production environments anyway.

Question 2 - Email will not continue to flow because CAS server is required because it hosts all of the virtual directories like autodiscover, EWS, EAS etc. CAS also creates perisitent connections to the database where the mailbox resides so CAS is required.

Hmmm... I just found out that all the databases are active on what I thought was the secondary server, however owa is on the other server. OWA does not appear to be functioning on the secondary server. I know how to make the necessary DNS changes to point to the secondary server. However I get the following screenshots when trying to get to the OWA site.

If you have CAS role installed on the second server you need to configure load balancing using a hardware load balancer. You will also need to configure your Virtual directories on the client access server and also need to make sure that you have the proper certificate installed on this server as well.
