Re: [ofa-general] Re: [PATCH v2] infiniband-diags/scripts: Add 'ibcheckspeed' and 'ibcheckportspeed' to scripts

[Barry Mavin <Barry.Mavin@recital.com>]

I use mellanox connectx cards and switches in a cluster.

When I try and use ibtracert I get this output.

# ibtracert 10.10.10.1 10.10.10.3
ibwarn: [6998] _do_madrpc: recv failed: Connection timed out
ibwarn: [6998] mad_rpc: _do_madrpc failed; dport (Lid 10)
ibwarn: [6998] find_route: can't reach to/from ports
ibtracert: iberror: failed: can't find a route to the src port

Does anyone have any idea why this would be happening?
