Network Card teaming in Linux

michael fenton — Sat, 29 Sep 2007 16:37:19 GMT

Hi All,

I've just installed Linux Redhat ES 4 update 4 on a DL380 G5 Server and updated with the Proliant support pack (PSP) .How do I team network cards .Does the PSP install a network management tool for doing this? I cannot see it.

(Unfortunately my knowledge of Linux is petty limted and this is my first installation)

Any help would be appreciated

Bonding is really easy in linux. I've got BL25's and BL45's bonded now on Redhat 4.4.

Look for the file:

/usr/share/doc/kernel-doc-2.6.9/Documentation/networking/bonding.txt

Config files will be somewhere like /etc/sysconfig/networking/devices (you can type "locate eth |grep etc" to find them easily - or you can use the redhat tool "system-config-network" to set one eth interface up, and then search for it (after running "updatedb".

You need to set the actual NIC's (eth0, eth1)
as something like this:

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
SLAVE=yes
TYPE=Ethernet

Then make a config file in the same directory called "ifcfg-bond0" with something like this:

DEVICE=bond0
IPADDR=IPADDR
NETMASK=MASK
NETWORK=NETWORK
BROADCAST=BROADCAST
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet

You also need to make the bonding module load by adding "alias bond0 bonding".

You also need to tell the config how to determine if a link has failed. There are a number of options.

Check out the txt file above for the full info.

Once you think you've got it right, reboot. Make sure you've got ilo working or a monitor/keyboard on the server in case you get it wrong.

Let me know if you have any problems.
