Different interfaces need to be declared with different LNET networks - something like "networks=tcp0(eth0),tcp1(eth1)". Of course, that assumes your clients are configured to use a mix of tcp0 and tcp1 for connections (with each client only using one of the two). This is really only useful in corner cases, when you're doing something strange; if eth0 and eth1 are in the same subnet (as in your example), this is almost certainly not productive.
A better bet might be to use a single LNET, and bond the two interfaces together - either as an active/passive pair, or active/active (e.g., LACP). Then you'd declare networks=tcp0(bond0), give the bond a single IP address, and client traffic would be split across the two members in the bond more like you probably expect (given the limits of the bond protocol you're using). -- Mike Shuey On Tue, Jun 25, 2013 at 8:06 AM, Alfonso Pardo <[email protected]>wrote: > hello friends, > > I need to comunicate my OSS by two ethernet TCP interfaces: eth0 and eth1. > > I have configured this feature in my modprobe.d with: > > “options lnet networks=tcp0(eth0,eth1)” > > And I can see two interfaces with: > > lctl --net tcp interface_list > sa-d4-01.ceta-ciemat.es: (192.168.11.15/255.255.255.0) npeer 0 nroute 2 > sa-d4-01.ceta-ciemat.es: (192.168.11.35/255.255.255.0) npeer 0 nroute 0 > > But, the clients only can communicate with the first interface: > > lctl ping 192.168.11.15 > 12345-0@lo > 12345-192.168.11.15@tcp > lctl ping 192.168.11.35 > failed to ping 192.168.11.35@tcp: Input/output error > > > Any suggestions how to “enable” the second interface? > > > thank in advance > > *Alfonso Pardo Diaz * > *System Administrator / Researcher * > *c/ Sola nº 1; 10200 TRUJILLO, SPAIN * > *Tel: +34 927 65 93 17 Fax: +34 927 32 32 37 * > > [image: CETA-Ciemat logo] <http://www.ceta-ciemat.es/> > > ---------------------------- Confidencialidad: Este mensaje y sus ficheros > adjuntos se dirige exclusivamente a su destinatario y puede contener > información privilegiada o confidencial.
