SolutionFirst, you must update the ethernet adapter driver with bcm5700 provided by hp (www.hp.com/linux => drivers).
Then, make sure that the proper driver is in use in /etc/modules.conf (alias ethX bcm5700).
Stop networking and remove the previously used module :
/etc/init.d/network stop
rmmod tg3 (or bcm5700)
Back-up your network configuration files :
cd /etc/sysconfig/network-scripts
mkdir /tmp/network-sav
cp -p ifcfg-* /tmp/network-sav
Edit the configuration files :
ifcfg-bond0 :
IPADDR=...
NETMASK=...
NETWORK=...
BROADCAST=...
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
ifcfg-eth0 and ifcfg-eth1 :
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
Edit /etc/modules.conf :
alias bond0 bonding
For other bonding driver options, type :
modinfo bonding
Start the network :
/etc/init.d/network start
Good luck.

Re: Ethernet Failover configuration
I tried the opton by using a PC. But facing some problems.
____________________________________________
*********************************************
I used two Intel pro/100 cards to configure ethernet fail over. The steps done are:
1. took the backup all configuration file
2. Configired both cards.
Then the entries for those cards in /etc/modules.conf were :
alias eth0 e100
alias eth1 e100
3. Stopped the network (/etc/init.d/network stop)
and run command,
rmmod e100
4. edited /etc/sysconfig/network-scriptss/ifcfg-eth0
The exact entries are:
DEVICE=eth0
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
TYPE=Ethernet
USERCTL=no
5. edited /etc/sysconfig/network-scripts/ifcfg-eth1
same entries like above ,only diff is DEVICE=eth1
6. Edited /etc/sysconfig/network-scripts/ifcfg-bond0
The exact entries are:
ONBOOT=yes
BOOTPROTO=none
IPADDR=172.20.5.5
NETMASK=255.255.0.0
GATEWAY=172.20.1.1
TYPE=Ethernet
USERCTL=no
NETWORK=172.20.0.0
BROADCAST=172.20.255.255
PEERDNS=no
7.Added entry in /etc/modules.conf
alias bond0 bonding
8. Started the vetwork (/etc/init.d/network start)
But giving error and not starting the network service,
The mesages while starting the network service,
Setting network parameter [ok]
Bringing up interface lo [ok]
Bringing up interface bond0 :Usage :Grep [OPTION]--PATTERN [FILE]---
Try 'grep --help' for more information
Failed to Bring up.
Not enough of information : "dev" argument is required
Bringing up interface eth0 [ok]
Bringing up interface eth1 [ok]
_____________________________________________
*********************************************
So what could be the mistake I did...
Please advice ..
Thanks in advance..

Re: Ethernet Failover configuration
When I added the entry,
DEVICE=bond0
in the file /etc/sysconfig/network-scripts/ifcfg-bond0 ,it is found working!
But if we keep only one connection (To any of the cards) 50 % package drop is happening. If both are connected 0%. Why it is so?
Any way thank you very much.
Cheers
