ibcheckroutes validates route between all hosts in the fabric.
This script finds all leaf switches (switches that are connected to HCAs)
and runs ibtracert between them.
When using various routing algorithms (e.g. up-down),
if fabric topology is not suitable there will be no
routes between some

CAs or HCAs ?
What about switch port 0s ?

I think depending on the kernel you're running on, you might have to add -i.

So I accepted that I'd have to move Fedora version to get OFED
support... and I was ok with that. However, I see now that FC12 is not
released, and won't be until November. I have tested FC11, and it
doesn't work w/ the OFED 1.5 beta1 either. It seems OFED has skipped
out on support for Fedora

Hello,
Anybody has seen lro doesn't work for port2 but works for port1 before?
We found this issue on RHEL5.
Thanks

Fails w/ ofa_kernel like the others have... I didn't test excluding
this rpm with FC11, but the others also fail elsewhere w/ this rpm
excluded- so I'm guessing FC11 would as well. I included the output
(and last 50 lines of log) in case you can glean something useful from
it. Thank you-
Additionally, I'd be happy to set up an FC11 sandbox system and give
you access if it's any help.

by lro not working -- the interface doesn't work with lro

Dumb question: what was the MTU setting of the eth interface associated
with port 2? Dropping jumbo frames has nothing to do with LRO - it is
plain layer 2 functionality.

The -I option is not recognized with nfs-utils 1.1.6, neither is the -o rdma
option.
Is there any special option that should be used on the client mount command
to tell it to use rdma?

Shirley,
Are you referring to actual Ethernet frame size or to TCP message size?
If the port MTU set to 1500 it will reject Ethernet frames larger than
this size, this has nothing to do with the LRO.
LRO is a TCP offload that improves CPU utilization on the TCP receiver
by combining multiple

Configure your Subnet Manager (SM) to set the MTU value in

My badness. I have not used 'iblinkinfo' before.
So, I guess there is no need for the above script. Apart from that, I feel
there should be a program/script which will first scan the fabric to find the
maximum common supported width/speed and then report the warning messages
of the links/ports
