As far as i know NetApp's filer does not have ipoib .
You must have ATS in your system in order to work.
if you are using opensm try to enable debug and check that both sides 
register ATS servise record "set" and that your system get correct reply to
the ATS "get".

My server is a netapp filer. I attached the IP address to the interface,
10.10.10.11 but the ping fails..

Also, with the correct IP address, I can now post a connect request, but 
it never gets
back with a response (other than timeout). Unfortunately I do not 
control the server,
so I have no way of confirming if it is sent out.

I am now trying against an identical OpenIB instance. I will let you 
know the result.

Thanks
