Removing a replica from a SQL Server Availability Group

Before you begin

You must have a a SQL Server Availability Group with three or more replicas. This is because an Availability Group must have at least two replicas, and BDA does not allow you to remove any replicas if the result is fewer than two.

To remove a replica from a SQL Server Availability Group

1. From the Management Console, navigate to the Availability Group on which you want to remove the replica.
2. Select Provision > Remove Replica from SQL Server Availability Group.

3. In the General page, populate the following fields, and click Next.

4. In the Replicas Selection page, populate the following fields, and click Next.

5. In the Custom Scripts Configuration page, select any pre-provisioning or post-provisioning scripts that you want to run as follows, and click Next.

6. In the Job Options page, specify any of the following Job options, and click Next.

7. If the Change Control page displays, populate the following fields, and click Next.

   Note

   The Change Control page appears only when change control is configured for your environment. See Configuring-change-control.

8. In the Summary page, review the provisioning information.
   To make changes, do the following:
   1. Click Go to to return to the provisioning step that you want to edit.
   2. Make your changes.
   3. Click Save and Review to return to the Summary page.
9. Specify your verification preferences.
   For additional information, see Understanding-pre-verification-tests.
   • To continue with removing the replicas from the availability group after the pre-verification tests have been successfully run without manual intervention, select Automatically Continue If All Tests Succeed.

   • To remove the replicas from the availability group without having first run the pre-verification steps, select Skip Pre-Verification Tests.

     Note

     The Skip Pre-Verification Tests option should only be used when you are certain all tests can succeed. The option skips verification and advances directly to the actual provisioning activity.

10. Click Remove Replica from SQL Server Availability Group.
    A progress page appears followed by a success message upon completion. The replicas no longer appears in the Contents page for this SQL Server Availability Group.
