3.4.0 Matrix Server Administration Guide

Chapter 4: Configure Network Interfaces 48

If Matrix Server must use a network that was configured to discourage

administrative traffic, it will fail over to a network that allows the traffic

as soon as that network becomes available to all servers in the matrix.

If multiple interface failures occur on a server and there is not another

network available for the administrative network, the server may drop

out of the matrix. The remaining servers will continue to use the existing

administrative network.

Making Network Changes

The following network changes should not be made while Matrix Server

is running. Attempting to do any of the following can adversely affect the

entire matrix. If you need to perform these actions on a particular server,

first stop Matrix Server on that server. Then make your change and restart

Matrix Server.

• Add or delete a network interface from the operating system.

• Change network properties on the Network Control Panel.

• Disable or re-enable a network interface via the Device Manager.

• Update network drivers.

• Hot-swapping of PCI cards.

Add or Modify a Network Interface

When you add a server to the matrix, its network interfaces are

automatically configured into the matrix. Occasionally, you may want to

preconfigure a network interface. For example, you can add a network

interface that either does not currently exist on a server, or that is on a

server that is down. You might also want to modify an existing interface.

• To add a network interface, select the server for that interface on the

Servers window, right-click, and select Add Network Interface.

• To modify an existing network interface, select that interface, right-

click, and select Properties. The network interface must be down; you

cannot modify an “up” network interface.
