2. Determine the interface device name for each physical Ethernet interface on this

newly installed adapter. See

‘‘Determining Interface Device Names’’ on page 5-30

for details.

You must add this device name to the physical interface’s configuration file (see

step

5).

3. Repeat steps 1 and 2 for the second adapter in the corresponding slot in the

second paired CPU-I/O enclosure.

4. Create a new bond file (for example, ifcfg-bond2) in the

etc/sysconfig/network-scripts directory. Use the contents of an existing

bondn file as a guide.

5. Create two new physical interface configuration files for the two new physical

interfaces. Use the contents of an existing ifcfg-eth* file as a guide. Be sure to

use the device names of the newly installed adapters (see step

2).

6. Type the following command to bring up the new interface:

# ifup bond2

MAC Addresses

You can use the ifconfig command to determine the current MAC address of an

Ethernet interface. Alternatively, you can examine the interface’s address file in the

sys/class/net/interfacename directory.

For the embedded Ethernet adapter interfaces, Ethernet MAC addresses are

algorithmically generated from a base MAC address assigned to the machine as a

whole. Each physical device receives a different MAC address. Because of this, a

channel-bonding interface (and all of its physical devices) may get a different MAC

address from one reboot to the next, depending on which physical device is available

first (based on which CPU-I/O enclosure is used during the boot).

Other System Configuration Information

In addition to setting up storage and network devices, you may want to perform the

following tasks to set up your system:

•

Configure ftlSNMP to allow remote management of your ftServer system. See

Chapter 8 for instructions.

•

Disable hyperthreading.

Information about video display settings is also included.
