How to Restart a Passive Server with Neverfail Continuity Engine Installed

Summary
This Knowledgebase article provides information on how to restart a Passive server running Neverfail Engine.

More Information

When restarting a server running Neverfail Engine, it is important to follow the recommended procedure to prevent an Unclean shutdown of Neverfail Engine, which may result in some data loss.
The following procedure assumes that the Neverfail Engine servers are running in a pair with the Primary server as Active and the Secondary server as Passive.

Procedure

To restart the Secondary (passive) server, follow the steps below:
  1. Stop Neverfail Engine on Secondary (passive) server. To do this:
    1. Launch the Neverfail Advanced Client, by right-clicking the Neverfail system tray icon and selecting Launch Advanced Management Client or by selecting the Windows option from Start > All Programs > Neverfail.
    2. Login at the prompt if necessary. Select the server group you wish to manage and double-click to open.
    3. On the Server:Summary page, check that the File System Status and Registry Status are both shown as Synchronized and then click Shutdown.
    4. Note: The option to leave protected applications running when shutting-down Neverfail Engine can be configured by clicking the Configure button on the Server: Summary page.
    5. At this point select the option to shutdown the Secondary server.
  2. Ensure the 'NFServerR2' service is set to Automatic, from within the Windows Services Management Console and check that the settings are correct in the Neverfail Configure Server Wizard. To do this:
    1. Right-click the Neverfail 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 Engine).
    3. Click Finish.
    4. 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. The Services that are protected by Neverfail Engine are listed on the Applications: Services page of the Neverfail Advanced Management Client.
  5. Log into the server pair, and check that the servers have connected and started replication. To do this:
    1. Launch the Neverfail Advanced Client, by right-clicking the Neverfail system tray icon and selecting Launch Advanced Management Client, or by selecting the Windows option from Start > All Programs > Neverfail .
    2. Login at the prompt if necessary. Select the server group you wish to manage and double-click to open the Server: Summary page.
    3. On the Server:Summary page, 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.
  6. Logout of the Neverfail Advanced Management Client by selecting Close, and following the on screen prompts.
