If a failover occurs, a message is written to the NT Event Viewer log. In addition, if the
Enable for DMI / Hot Swap Support checkbox is checked, a DMI alert will also be
generated.

From the Windows NT Server desktop, select Control Panel, then select the
Network icon, then select the Adapters tab.
Highlight one of the adapters that will be in the redundant pair and then click the
Properties... button.
Check the Grouping box. This will show the possible combinations for redundant
pairs.
Select the adapter pair you want and then select OK. Note that the integrated
Ethernet controller is located at PCI bus A, slot 2.
Two options are available for recovering from a failover condition. The options
are determined by the Enable for DMI / Hot Swap Support checkbox. If the IBM
Netfinity Hot Plug PCI for Windows NT Server 4.0 package is installed, this
checkbox will appear at the bottom of the Adapter Properties panel. If you do not
have the IBM Netfinity Hot Plug PCI for Windows NT Server 4.0 package
installed on your server, you will not see the Enable for DMI / Hot Swap Support
checkbox.
If the Enable for DMI / Hot Swap Support checkbox is not checked or is not
present, traffic will automatically switch back to the primary adapter when the
primary link status is restored. In this mode, the adapter cannot be hot-swapped.
Users with the IBM Netfinity Hot Plug PCI for Windows NT Server 4.0 package
installed should check the Enable for DMI / Hot Swap Support checkbox.
If the Enable for DMI / Hot Swap Support checkbox is checked, traffic will
remain on the secondary adapter until the user directs it to return to the primary
adapter. This can be done after the hot-swap replacement of the primary adapter
or by using the DMI interface.
Select Close to exit from the Network setup.
When you restart the server, the failover function will be in effect.
provided with the adapter.
Load the device driver by using the following command:
LOAD d:\path\PCNTNW.LAN PRIMARY=x SECONDARY=y
where d and path are the drive and path where the driver is located, and x and y
are the PCI slot numbers where the redundant pair is located.
The slot number associated with the integrated Ethernet controller can vary
depending on the configuration of the server. To determine the slot number, load
the driver with no parameters. The driver will display the available slot numbers.
The slot number that is greater that 10000 will be the slot number of integrated
Ethernet controller. When the slot number of the integrated Ethernet controller is
determined, reload the driver with the appropriate parameters.
When the driver is loaded, bind it to a protocol stack.
The operating system console generates a message.
The custom counters for the device driver contain variables that define the state of
the failover function and the location of the redundant pair. You can use the
NetWare Monitor to view the custom counters.
