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. 8. Select Close to exit from the Network setup. When you restart the server, the failover function will be in effect. 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. IntraNetWare: 1. Add the redundant NIC adapter according to the instructions that are provided with the adapter. 2. 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. 3. When the driver is loaded, bind it to a protocol stack.

Hardware Maintenance Manual: Netfinity 4500R Type 8656
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.
8.
Select
Close
to exit from the Network setup.
When you restart the server, the failover function will be in effect.
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.
IntraNetWare:
1.
Add the redundant NIC adapter according to the instructions that are provided
with the adapter.
2.
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.
3.
When the driver is loaded, bind it to a protocol stack.
The failover function is now enabled. If a failover occurs:
•
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.
Note:
If the primary adapter was hot-replaced while the Ethernet traffic was being
handled by the secondary Ethernet controller, the traffic does not
automatically switch back to the primary adapter when the primary adapter
comes back online. In this case, issue the command:
LOAD
