I'm attempting to set up an infiniband connection between two MHQH19B-XTR adapters and I'm not having any luck getting a link up. I suspect that some piece of hardware is bad, but I'm not sure how to tell if it's the cable or one/both of the adapters.
I have the Mellanox OFED package installed on both the server (Ubuntu 12.04) and on the client (Windows 8) and connected with a Mellanox QSFP/QSFP optical cable.
On both the server and client, ibstat just shows the state as being "Down" and the physical state as "Polling." There doesn't appear to be any evidence that the cards can see each other. I have the included subnet manager running on the Ubuntu side. The opensm logs say "SM port is down."
Can anyone provide me with some guidance on how to diagnose this? Unfortunately I don't have any way to test this cable.
