Re: Can ping but not connect to ports using infiniband

Yeah, as Yair Ifergan mentioned, don't connect port 0 to port 0, then port 1 to port 1.

 

If you're connecting two boxes directly to each other, connect both of their port 0's to port 1 on the other.  eg Kind of like crossing over the cables.  Then run OpenSM (opensmd) on both.  That way all 4 ports should come up as "ACTIVE".

 

I do this (using RHEL/CentOS) and it works fine with IPoIB layered on top.  I can give you the CentOS ifcfg-ethx files, but I'm not sure they'd be helpful as Debian/Ubuntu does networking differently.
