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
