Setting Up the ftServer System

N O T E S
1. There must be at least one alias for an active bond in
the
/etc/modprobe.d/ft-network.conf
file, or
bonding cannot occur.
2. The
/etc/modprobe.d
directory should contain no
more than one
ft-network.conf
file.
Determining Interface Device Names
When you add a PCI Ethernet adapter to a system, you must determine the device
names of the physical interfaces on the adapter before you can configure it. See
Figure 7-1
and
Figure 7-2
for the hardware device path of PCI Ethernet adapters,
and then refer to
Table 5-2
to determine the device names.
When installing a PCI adapter, you can use the output of the
lspci
command to
confirm its Ethernet interface device name. By comparing the output of
lspci
before
and after installing the adapter, you can identify the newly displayed output that
corresponds to the newly installed adapter. The output might look like the following:
04:02.0 Ethernet controller: Intel Corp. 82546EB Gigabit
Ethernet Controller (Copper) (rev 01)
The device names for the two physical interfaces on the newly added, dual-Ethernet
adapter shown above are eth000008 and eth000009.

Issuing an
lspci
command with the
-xxx
option may
temporarily interfere with the fault-tolerant operation of the
system. To avoid this problem, never type the
lspci
command with the
-xxx
option.
To add two physical interfaces and configure a new channel-bonding interface
1. Install the first Ethernet PCI adapter in a supported slot in one CPU-I/O enclosure.
N O T E
When adding a pair of Ethernet PCI adapters to the
system, be sure to install one adapter in the upper
CPU-I/O enclosure and the other in the lower CPU-I/O
enclosure, in same-numbered slots. This is necessary to
maintain fault tolerance. If you install both devices in the
same enclosure, and that enclosure fails, you will lose
connectivity.
