Testing Datacenter Failover

    Question

  • Hello All,

               I have two MBX on primary site and one MBX on the DR Site.  All three servers are part of the same DAG and are on different active directory sites.  The DAC mode is enabled on the DAG.  I want to test out the DR Scenario.  Can anyone list down the steps?  Thanks.

  • Hi

    Do you also have the HUB/CAS role installed on the MXB server or on a separate server in your DR site?

    In this case if clients are able to connect to the failover site and the CAS and HUB roles are configured properly, you should be able to just make the DB's on the DR site active.

    Please see http://technet.microsoft.com/en-us/library/dd979799.aspx for more info.

    Good luck

  • Thanks for the replies.

    No HUB AND CAS are on different servers.

    Through Technet Articles above.  I have formed following steps.  Kindly, confirm they are sufficient:

    FAILOVER

    ======

    Site A
    ====
    1-  Stop-DatabaseAvailabilityGroup –Identity DAG01 – ActiveDirectorySite SiteA –ConfigurationOnly

    Site B

    ====
    1-  Stop-DatabaseAvailabilityGroup –Identity DAG01 – ActiveDirectorySite SiteA –ConfigurationOnly
    2-  Stop Cluster Service
    3-  Restore-DatabaseAvailabilityGroup –Identity DAG01 –ActiveDirectorySite SiteB
    4-  Move Active Mailboxes to SiteBMBX

    FAILBACK
    ======
    1-  Restart MBX Servers on SiteA
    2-  Start-DatabaseAvailabilityGroup DAG01 –ActiveDirectorySite SiteA
    3-  Dismount Databases on SiteB and Move them to SiteA

  • That look OK.  Dont forget the the little check like FSW config if using even nodes and general health checks.

  • Yes.  The steps work.  The only thing to remove from steps is stoppage of cluster service.  It is not required in SP1 AND SP2 BOXES.  hope this helps.
