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.

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? -- Lukáš Hejtmánek Linux Administrator only because Full Time Multitasking Ninja is not an official job title _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
