[Lustre-discuss] Adding additional ethernet ports to OSS

[Jerome, Ron]

I have a Lustre (1.6.4.3) system consisting of an MGS/MGT node and 4 OSS nodes.  I have just added an additional dual port Ethernet board to each of the OSSs, so they now have 3 Ethernet ports (eth0,eth1,eth2) instead of just one.  
 
My question is how do I get lnet to use them all.  I have added options tcp0(eth0,eth1,eth2) to the modprobe.conf file and "lctl interface_list" shows all three, but it appears that all the traffic is still going over eth0 and eth1 and eth2 are not being used.
 
Do I need to do a writeconf on the MGS to get these new boards recognised?
 
Thanks in advance,
