[Lustre-discuss] How do you make an MGS/OSS listen on 2 NICs?

I am running on CentOS 5 distribution without adding any updates from CentOS. I am using the lustre 1.6.4.1 kernel and software.

I have two NICs that run though different switches.

I have the lustre options in my modprobe.conf to look like this:

options lnet networks=tcp0(eth1,eth0)

My MGS seems to be only listening on the first interface however.

When I try and ping the 1st interface (eth1) , it works when I go for the second (eth0) it does not.

# lctl ping 192.168.135.81 at tcp<mailto:192.168.135.81 at tcp>
12345-0 at lo<mailto:12345-0 at lo>
12345-192.168.135.81 at tcp<mailto:12345-192.168.135.81 at tcp>
# lctl ping 192.168.135.80 at tcp<mailto:192.168.135.80 at tcp>
failed to ping 192.168.135.80 at tcp<mailto:192.168.135.80 at tcp>: Input/output error

The following is in /var/log/messages

Jan 15 17:18:15 dint0001 kernel: LustreError: 120-3: Refusing connection from 192.168.135.80 for 192.168.135.80 at tcp<mailto:192.168.135.80 at tcp>: No matching NI

Where/How do I configure it to listen on both devices?

Thank you!
