[gpfsug-discuss] Multihomed nodes and failover networks

If IB is enabled and is setup with verbs, then this is the preferred network. GPFS will always fail-back to Ethernet afterwards, however what you can't do is have multiple "subnets" defined and have GPFS fail between different Ethernet networks.

    Hello,
    
    does anyone know whether there is a chance to use e.g., 10G ethernet together
    with IniniBand network for multihoming of GPFS nodes?
    
    I mean to setup two different type of networks to mitigate network failures.
    I read that you can have several networks configured in GPFS but it does not 
    provide failover. Nothing changed in this as of GPFS version 5.x?
