It is a good idea to reboot both Switch Blades after configuring them for surviving partner mode, in order to
ensure that there were are no problems with the installation. Before rebooting the Switch Blades, however, it
is important to save the changes made to the Switch Blade by using the zsync command as follows:
zsync

The HP bc2100 ATCA Server Blades The HP bc2100 ATCA Server Blades running the Linux operating
system can take advantage of ATCA Switch Blades that are configured for HA operation by enabling the
network bonding driver. The bonding driver is a Linux kernel driver that creates a logical network interface
by aggregating multiple physical network interfaces.
Source code and general information about the Linux bonding driver can be found at:
http://sourceforge.net/projects/bonding/.
A Linux document explaining how to enable the bonding driver can be found at:
http://www.kernel.org/pub/linux/kernel/people/marcelo/linux-2.4/Documentation/networking/bonding.txt
Example Usage of the Linux Bonding Driver This example usage of the Linux Bonding Driver makes
the following initial assumptions:
• The HP bc2100 ATCA Server Blade is running the Linux OS.
• That the Linux Server Blade eth0 is a physical network interface that is connected to the left Ethernet
Switch Blade installed in 14-Slot Shelf blade cage physical slot 7.
• That the Linux Server Blade eth1 is a physical network interface that is connected to the right Ethernet
Switch Blade installed in 14-Slot Shelf blade cage physical slot 8.
With the above assumptions in force, complete the following steps to set up the Linux Bonding Driver:
Step 1. Enter the following commands to create bond0, a logical network interface, that aggregates eth0
and eth1:
modprobe bonding # Load the bonding driver into kernel memory
ifconfig eth0 up# Set eth0 status to up
ifconfig eth1 up# Set eth1 status to up
#
# Configure bond0 as a logical interface
#
ifconfig bond0 10.35.50.xx netmask 255.0.0.0 up
#
# Enslave the physical network ports.
#
ifenslave bond0 eth0# Add physical eth0 to bond0
ifenslave bond0 eth1# Add physical eth1 to bond0
