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
bond
n
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.
