Hi Kevin, You’ll definitely need to have tcp on the server interface used for the clients accessing Lustre over the gateway (really an InfiniBand-Ethernet bridge). I don’t know of any problem having both protocols (tcp and o2ib) on the same interface but you could also add an alias or child interface (e.g., ib0:0 or ib0.8001) if you wanted to keep things separated.

The gateway extends the same layer-2 IP range that's being used for IPoIB out to the Ethernet clients How should I go about doing this? Since the clients don't have IB, it doesn't appear that I can use o2ib0 to mount. Do I need to add another lnet network on the servers? Something like options lnet networks=o2ib0(ib0),tcp0(ib0)? Can I have both protocols on the same interface? And if I do have to add another lnet network, is there any way to do so without restarting the servers?
