<p class="MsoNormal">Looks like you are telling GPFS to use an MLX card that doesn’t exist on the node, this is set with verbsPorts, it’s probably not your issue here, but you are better using nodeclasses and assigning the config option to those nodeclasses
that have the correct card installed (I’d also encourage you to use a fabric number, we do this even if there is only 1 fabric currently in the cluster as we’ve added other fabrics over time or over multiple locations).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Have you tried using mmnetverify at all? It’s been getting better in the newer releases and will give you a good indication if you have a comms issue due to something like name resolution in addition to testing between nodes…<o:p></o:p></p>
