Hello.
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?
root@node3:~/ibdump-1.0.5-4-rpms/ibdump-1.0.5-4.x86_64-rhel6/usr/bin# ./ibdump ------------------------------------------------ IB device : "mlx4_0" IB port : 1 Dump file : sniffer.pcap Sniffer WQEs (max burst size) : 4096 ------------------------------------------------ Initiating resources ... searching for IB devices in host Warning: memory access to device mlx4_0 failed: Input/output error. Warning: Fallback on IO: much slower, and unsafe if device in use. -E- Failed to open mst device mlx4_0: No such file or directory -E- failed to create resources
I've tried to execute the ibdump utility (from all the RPMs that were in the download). But it fails. with this:
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.
