Determining the Primary and Secondary Network Adapters

Creating a New Network Adapter Team Using the Procfg Application

An issue exists if the procfg application is used to create a new network adapter team. If both network adapters are added to the team, the procfg application switches the MAC addresses of the two adapters making the team unusable by the operating system. The affected driver revisions are listed below.

•Procfg 2.2.19

•E1000 5.3.19-1

•Ians 3.4.2a-2.4.21_4.EL

Future releases of these drivers will not be affected.

Two workarounds exist until the new drivers are available:

•Add one network adapter to the team, save the team information, and then add the second adapter.

•Modify the /etc/procfg/team name file, where team name is the name of the new network adapter team, and correct the MAC addresses.

Determining the Primary and Secondary Network Adapters

During a Microsoft Windows 2000 or Windows Server 2003 operating system installation, the operating system enumerates physical network adapters, but may list them in random order. This can cause confusion when setting up and testing a network adapter team for failover/failback. This may also cause misunderstandings as to which cable is the primary or the secondary network adapter team member and cause unexpected team behavior when a cable is disconnected or connectivity is interrupted.

To help determine the identities of physical network adapters, right-click and rename the adapters in Network Connections in the Control Panel, use the ipconfig /all command to note the IP-to- MAC address assignments of the adapters, and then use the IP addresses to locate the adapters in Network Connections.

For a system with integrated network adapters, LOM1 has the lowest MAC address. The link status indicators can also be used to externally identify the adapters to the system. Additionally, an integrated network adapter’s MAC address is listed in the System Setup program.

NOTE: Occasionally during an operating system installation, the network adapters may be incorrectly assigned and cause IP address conflict messages to appear during boot. If this occurs, use the procedures listed above to correctly assign the network adapters.
