You may upgrade from the following Neverfail versions to V4.3.3 using this upgrade patch:

  • V4.1 SP1
  • V4.2
  • V4.3.1
  • V4.3.2

The upgrade patch does not work on pre-V4.x kits. You cannot upgrade from any Neverfail Heartbeat V3.x.

Please Note: You should not execute this patch more than once on the same machine.

The upgrade patch can be installed on Microsoft Windows 2003 SP1. The upgrade patch may be executed using Windows Terminal Services or Remote Desktop if required, though you should bear in mind that it may be necessary to disconnect the passive server from the network physically.

Procedure

Before You Begin

  • Ensure you have read and fully understood the instructions below before attempting to install this patch.
  • It is necessary to reboot both servers during the upgrade process, as Neverfail Heartbeat drivers are updated on both active and passive servers. Subsequently, a small amount of downtime will be incurred.

How To Apply The Neverfail V4.3.3 Patch To A Server Pair

To apply the Neverfail 4.3.3 patch to your system successfully, please perform the steps listed below.

On a remote client PC, or the active server, as appropriate:

  1. Download V4.3.3-patch.zip from the appropriate product area of the Neverfail Extranet. Extract the file V4-3-25412-patch.exe to both your active and passive servers, and to any remote client PCs running the Neverfail Heartbeat Management Client.
  2. Shutdown Neverfail Heartbeat, and close any other applications you may have open on the active and passive servers.
  3. On the passive server:
    1. Disconnect the principal (public) network card on the passive server from the network. This may be done by unplugging the network cable, or by disabling the network card.
    2. Execute the patch on the passive server by double-clicking on the file V4-3-25412-patch.exe. Follow the instructions displayed to install the patch.
    3. Reboot the passive server when prompted. After the reboot, the upgraded version of Neverfail Heartbeat will be running on the passive server, which is still disconnected from the network.
    4. Right-click on the Neverfail System Tray icon, and select 'About Neverfail Heartbeat'. Check that the version displayed is V4.3 (build 25412).
    5. Type the following from a Command prompt:

      'C:\Neverfail\R2\bin\nfpktfltr.exe getstate'

      This should return the message 'Filter state is Filter'
  4. On the active server:
    1. Execute the patch on the active server by double-clicking on the file V4-3-25412-patch.exe. Follow the instructions displayed to install the patch.
    2. Reboot the active server when prompted. After the reboot, the upgraded version of Neverfail Heartbeat will be running on the active server.
    3. Right-click on the Neverfail System Tray icon, and select 'About Neverfail Heartbeat'. Check that the version displayed is V4.3 (build 25412)
    4. Type the following from a Command prompt:

      'C:\Neverfail\R2\bin\nfpktfltr.exe getstate'

      This should return the message 'Filter state is PassThru'
  5. On the passive server:
    1. Reconnect the passive server to the network
    2. Upgrade any remote client PCs running the Neverfail Heartbeat Management Client:
      1. Ensure that the Management Client is closed, and close any other applications you may have opened on the active and passive servers.
      2. Execute the patch on the remote client PC by double-clicking on the file V4-3-25412-patch.exe. Follow the instructions displayed to install the patch.
      3. Reboot the remote client PC when prompted.
  6. On a remote client PC, or the active server, as appropriate:
    1. Use the Neverfail Heartbeat Management Client to check that the Neverfail Channel is connected and that a full system check is in progress.

Note For Users Upgrading From Neverfail V4.1 SP1 And Neverfail V4.2

Neverfail Heartbeat V4.3.x versions support an extended set of configurable Alerts. In order to preserve your existing Alert configuration, the upgrade patch does not modify any Alert settings when it is installed. You should manually configure any additional alerts you require after installing the patch. This may be done from the 'Alerts' panel of the Neverfail Heartbeat Management Client.
