Not completely clear for me: does that mean that "active mode" makes it
send the totems systematically on both networks, and "passive mode" makes
it send on the first interface ringnumber (in openais.conf) and only on
the second interface rignnumber if the first is broken ?
Could someone give more precise information ?
or where can I find more information about this ?

And by the way, is there any issue to use to set the first interface
ringnumber
on Ethernet (eth0) and the second on IP/Infiniband ?

Thanks for your response.
Alain Moullé
