More Information

When restarting a server running Neverfail Heartbeat, it is important to follow the Neverfail recommended procedure to prevent an 'Unclean' shutdown of Neverfail Heartbeat, which may result in some data loss.

The following procedure assumes that the Neverfail Heartbeat server pair is running with the Primary server as active and the Secondary server as passive.

Procedure

Neverfail Heartbeat v6.2 and Later

To restart the Secondary (passive) server, follow the steps below:

  1. Stop Neverfail Heartbeat on Secondary (passive) server. To do this:
    1. Launch the Neverfail Heartbeat Management Client, by right-clicking the Neverfail Heartbeat system tray icon and selecting Manage Server , or by selecting the same option from Start > All Programs > Neverfail .
    2. Select the server pair you wish to manage and click Open .
    3. On the Server: Summary tab, check that the File System Status and Registry Status are both shown as 'Synchronized', and then click Shutdown .
    4. At this point select both the 'Primary' and 'Secondary' server option and select 'Do not stop protected applications'. This will leave the protected applications running on the active server as Neverfail Heartbeat exits on both servers.
  2. Ensure the 'NFServerR2' service is set to automatic, from within the Windows Services Management Console and check the settings are correct in the Neverfail Heartbeat configuration. To do this:
    1. Right-click the Neverfail Heartbeat system tray icon and select Configure Server wizard.
    2. From the Machine tab, check the server is set to passive. (This should already be the case if the server was passive before stopping Neverfail Heartbeat).
    3. Click Finish .

      Note: On Windows Server 2008, if any applications are running, you will be prompted to shutdown the application before shutting down or restarting Windows Server 2008.
  3. Restart Microsoft Windows as normal from the Start button.
  4. Following the restart, ensure that the appropriate protected services are NOT started on the Secondary (passive) server.
    1. Launch the Neverfail Heartbeat Management Client, by right-clicking the Neverfail Heartbeat system tray icon and selecting Manage Server , or by selecting the same option from Start > All Programs > Neverfail .
    2. Select the server pair you wish to manage and click Open .
    3. On the Applications: Services tab, check that the services are listed as running on the Primary (active) server and stopped on the Secondary (passive) server.
  5. On the Primary (active) server, start Neverfail Heartbeat. Right-click the Neverfail Heartbeat system tray icon and select Start Neverfail Heartbeat .
  6. Select the server pair and check that the servers have connected and started replication. To do this:
    1. Launch the Neverfail Heartbeat Management Client, by right-clicking the Neverfail Heartbeat system tray icon and selecting Manage Server , or by selecting the same option from Start > All Programs > Neverfail .
    2. Select the server pair you wish to manage and click Open .
    3. On the Server: Summary tab, check that the File System Status and Registry Status are both replicating and the direction is from Primary (active) to Secondary (passive). The Registry Status should quickly display as 'Synchronized'. The File System Status may take much longer depending on the amount of protected data.
  7. Close the Neverfail Heartbeat Management Client by selecting File > Exit , and following the on screen prompts.
