Is ibdump in Mellanox OFED 2 supported in Ubuntu 14.04?

Question

I have Ubuntu 14.04. I have Mellanox Technologies MT27500 Family [ConnectX-3] HCAs. I was able to pass all the tests like ibping and ib_rdma_lat. Now I'm running MPI tests to verify that InfiniBand is working. How can I actually see that there is traffic going through the HCA's port?

I've tried to execute the ibdump utility (from all the RPMs that were in the download). But it fails. with this:

root@node3:~/ibdump-1.0.5-4-rpms/ibdump-1.0.5-4.x86_64-rhel6/usr/bin# ./ibdump
 ------------------------------------------------
 IB device                      : "mlx4_0"

-E- failed to create resources                                    

But there is actually the mlx4_0 device. As I said all the tests from the infiniband-diags package are passed.

Is ibdump supported in MLNX_OFED 2 in Ubuntu 14.04? If no then what alternatives can I use?

Thank you.

Answer 1

I believe you are missing the mst device because you don't have the mft package installed. Try to install the mft package, and start the mst module (you can use the mst start command to do that).

Answer 2

Mellanox answered my question http://community.mellanox.com/thread/1741.

The answer is that there is actually no ibdump for ConnetX-3 adapters for Debian/Ubuntu.
