How to Upgrade DAG Members In Exchange Server 2010 Part-2

As seen in part 1 we have the databases spread across both the nodes. lets go ahead and upgrade node2 to Exchange 2010 Sp2

Fig:2 Shows that the database are mounted on Node 1 and Node 2

Fig2 : Shows that the PAM or Cluster Group is on Node 2

Now lets run the StartDagServerMaintenance.ps1 from the scripts folder on Node2

image

Fig3: Shows the alert when the script runs. Also in the back ground its moving the Databases and the PAM role to Node 1

Fig 4: Shows that the databases and the PAM is moved to Node1

Fig 4 : Shows that the Node 2 is paused so that does not get activated

Fig 5: Shows that the Node 2 is Blocked for activation

Once the StartDagServerMaintenance.ps1 is run upgrade the Node2 Once it completes Run the StopDagServerMaintenance.ps1

How does the above script help us in upgrading the DAG nodes?

  1. Runs the Resume-MailboxDatabaseCopy cmdlet for each database copy hosted on the DAG member.
  2. Resumes the node in the cluster, which enables full cluster functionality for the DAG member.
  3. Sets the value of the DatabaseCopyAutoActivationPolicy parameter on the DAG member to Unrestricted

follow the same steps on  Node1 to get the Nodes upgraded to sp2

 

Happy Learning

Thanks
