We have Mellanox Connect-IB MCB194A-FCAT,FDR cards, and would like to run ibdump to diagnose message issues.
However, it seems like ibdump is searching for mlx4 device by default and may not support mlx5.
Running ibdump command, yields following error:
ibdump -d mlx5_0
Initiating resources …
searching for IB devices in host
-E- Unsupported HW devices id (1ff)
-E- failed to create resources
Here’s the output of ibstat:
CA ‘mlx5_0’
CA type: MT4113
Number of ports: 2
Firmware version: 10.10.4020
Hardware version: 0
Node GUID: 0xe41d2d030006d110
System image GUID: 0xe41d2d030006d110
Port 1:
State: Active
Physical state: LinkUp
Rate: 40 (FDR10)
Base lid: 1
LMC: 0
SM lid: 3
Capability mask: 0x0651484a
Port GUID: 0xe41d2d030006d110
Link layer: InfiniBand
Is ibdump supported on mlx5 devices?
Thanks -

Thanks - That’s good to know.
Is there any other mechanism that I can debug to see Infiniband multicast
traffic is working OK. I have apps on two machines which communicate
sporadically. I don’t think ethtool or ifconfig counters will display
Infiniband traffic stats. Is there any other way to diagnose until ibdump
is available.

As far as i know, the current driver is lacking the support for this functionality. The guys in Mellanox saying that it is expected to be support on the upcoming Mellanox OFED driver 3.0 (sometimes during Q2/2015)
Stay tune…
