Summary

This Knowledgebase article provides information about how removing or changing a NIC in the Primary or Secondary server can cause problems for the continued operation of the vCenter Server Heartbeat Packet Filter Driver.


More Information

Removing or changing a NIC in the Primary or Secondary server can cause problems for the continued operation of the vCenter Server Heartbeat  Packet Filter Driver if the correct procedures are not followed. Adding additional NICs does not cause any problems.

Procedure

Follow the steps below:

  1. Stop vCenter Server Heartbeat on the machine on which the modification is to take place.
  2. Before a NIC is replaced or removed, the vCenter Server Heartbeat Packet Filter Driver (nfpktfltr) must be uninstalled. To uninstall nfpktfltr, execute the command nfpktfltr.exe from the following location %installdir%\VMware\VMware vCenter Server Heartbeat\r2\bin with the following options as indicated below:

    Note: The version folder indicated (5.5.1507) may be different in your installation. Use the folder from your installation instead of that shown in the example.
  3. uninstall %installdir%\VMware\VMware vCenter Server Heartbeat\r2\drivers\nfpktfltr\5.5.1507 - uninstall nfpktfltr from all adapters

  4. Restart the server.
  5. Note: Care should be taken at this point if the server was passive before uninstalling the packet filter, as the IP address is no longer filtered.

    Replace or remove the desired NICs.

  6. When the network reconfiguration is complete, nfpktfltr must be reinstalled. To reinstall nfpktfltr, execute the command nfpktfltr.exe from the following location %installdir%\VMware\VMware vCenter Server Heartbeat\r2\bin with the following options as indicated below:
  7. install %installdir%\VMware\VMware vCenter Server Heartbeat\r2\drivers\nfpktfltr\5.5.1507 - install nfpktfltr

Note: If using teamed NICs, please refer to vCSHB-Ref-1646 - 'vCenter Server Heartbeat - How to install the Packet Filter Driver on a NIC team (Teamed NICs, NIC Teaming)'.
