How to: Verify Team Foundation Server Fail-Over in a Cluster

  • Article

By inspecting the status of the Team Foundation services on the application tier, you can verify that the cluster and the generic script resource work if the active node is taken offline. The procedure makes the following assumptions: Team Foundation Server is deployed in a complex topology that has the data tier in a cluster and not a single- or dual-server topology. The cluster administrator has added a generic script resource that resets the services on the application tier. If you do not have the generic script resource added to the cluster, you might experience a significant delay in recovery of services.

Required Permissions

To perform this procedure, you must be a member of the Cluster Administrator security group. For more information, see Team Foundation Server Permissions.

To take a node offline and test recovery

  1. On the application tier, open Windows Task Manager by right-clicking an empty area on the taskbar, and then click Task Manager.

  2. On the Processes tab, verify that IIS is running by locating w3wp in the Image Name column.

  3. On the active node of the data-tier cluster, open Cluster Administrator by clicking Start and then clicking Cluster Administrator.

  4. On the File menu, click Initiate Failover.

  5. On the application tier, open Windows Task Manager and verify that IIS w3wp no longer appears on the Processes tab.

  6. In the Cluster Administrator on the data tier, right-click the script resource and select bring online.

    Note

    The cluster may not have a script resource to explicitly restart the services. If not, you can add one by using the procedure, "How to: Accelerate Server Recovery in a Cluster" in the Team Foundation Server Installation Guide. Without this script, you may experience a significant delay before recovery has completed.

  7. In Internet Explorer on the application tier, locate the Web service and verify that GetRegistrationEntries is available.

    For example, you can enter the following Internet address to view the registration information for the application tier installed on the server ADATUM1.

    https://ADATUM1:8080/services/v1.0/registration.asmx
