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

[D. Marc Stearman]

Isaac is correct, that you will only have one NID, and it will be the  
only one pingable, however you should be able to use both interfaces  
with your configuration.  First of all, can you ping the IP addr (not  
using LNET pings, just ordinary tcp/ip ping)?

As you state, your server has two NICS on two different switches.   
Where is the client connected?  Does it have two NICS, and are they  
on the same switches?  Same subnets?  A bit more information about  
how your network is laid out would be useful.
