NIC Bonding oo Centos 6.0

We have two hp switches connected together with vrrp to provide redundant gateways, we have two HP 7000 blade enlosures, with two Gb2c switches each.

We need to set nic bonding on one of the blades running Centos.

Can you help?

So far we tried it on ubuntu and we only managed to get mode 3  to work, however once the server is rebooted one of the nics remains disconnected and we have to enable it manualy for redundancy to work. We tried other modes like mode 1 but we got 50% ping loss, it looks like its still loadbalancing on the offline link.

NOTE: Each blade has one nic on SW1 and another on SW 2 of the enclosure, which than connect to switch a and switch b. (Attached Diagram)

I do not think this is a network problem, most probably its a nic bonding config issue.

Blade switches had to be configured to monitor port 24 and bring the internal ports to a down state else the  serve would think that there was no nic failure.
