Bonding on linux.....again!

[Chris Rooney_1]

I have read several posts on bonding and had no not found any that seem to relate exactly to me problem. I have redhat linux enterprise 3 and installed the HP bonding drive for dl380.
I have set all the configuration files as stated in bonding.txt, but when I run network restart I get the error 'bonding device bond0 does not exist'

Any ideas?

Thanks

reat that too many times. Does red hat enterprise 3 support master/slave? or do I need to enter the commands manualy?
I have followed the instructions fully? From reading pther posts it seems there might be a conflict between the kernal and the driver. Is there a way to delete the hp driver and rely on the bonding that red hat provides? If so, how?

Thanks for your help

Hi,

It seems that the bonding driver is not automatically loaded (modprobe, insmod), therefore the network start script fails on bond0 device.
Check your syslog file to see what happens during bonding driver loading step.

Another tip : make sure that you use HP bonding driver with HP bcm5700 driver.
You can also try Red Hat's "tg3" driver with Red Hat bonding driver.
However, you cannot mix.

Last thing : after making changes in /etc/modules.conf, type "depmod -a".

Good luck,

Kodjo

cant you post-install or pre-install based on alias eth0 ?

i.e.

pre-install eth0 modprobe bond

? or alias eth0 as the bonding driver which pre-install's bcm5700..

just some thoughts.. never actually used it myself.

I'm running the exact same configuration (RH3 on the GL-380 G3) but I'm using the tg3 driver.. Instead of using 'alias eth0 tg3' & 'alias eth1 tg3' in the /etc/modules.conf file, you'll be using 'alias eth0 bcm5700' & 'alias eth1 bcm5700'. Sometimes its best to see actual working configuration files.

This first file is the bond0 file in /etc/sysconfig/network-scripts.
# Broadcom Corporation|NetXtreme BCM5703 Gigabit Ethernet
DEVICE=bond0
BOOTPROTO=none
HWADDR=00:0E:7F:22:D5:81
IPADDR=208.166.214.13
NETMASK=255.255.255.224
NETWORK=208.166.214.0
ONBOOT=yes
TYPE=Ethernet
USERCTL=no

Next is the ifcfg-eth0 file located in the same directory.
# Broadcom Corporation|NetXtreme BCM5703 Gigabit Ethernet
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes

Finally, the ifcfg-eth1 file.

# Broadcom Corporation|NetXtreme BCM5703 Gigabit Ethernet
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes

Hope this helps..

Started again and used the bonding driver that is provided by Linux....Works fine! Apparently there was a problem with that driver. Anyway thanks for your help.
