[ofw] Setting up Infiniband over WinXp- Help Needed

[Tzachi Dar]

Hi Ashwath,

There are a few things that I would like you to try:

1) Please run some low level IB test to see that traffic is indeed ok.
On one computer please run 

ib_send_bw -a

and on the other computer please run

ib_send_bw -a 192.168.0.x        (where x is the ip of the remote side.
Please start this test with the Ethernet addresses of the ports).
 
2) Assuming all works well please try to disable and enable the network
interfaces (ipoib) on both ports. Please see if this helps.
 
3) If this doesn't help, you will probably need to change the parameter
of "Guid bitwise mask" to e7. To do this, please open the device
manager, than go to "network adapters" select the ipoib interfaces and
than right click properties. Select the "Guid bitwise mask" and change
it to e7.
 
If all doesn't help, can you give me remote access to these stations?
 
Thanks
Tzachi

	Hi Fab,
	
	             I restarted opensm on the other node. I ran both
opensm and ibdiagnet on the other node (not on the node where opensm is
running). The logs are similar to the one I attached in my previous
mail. (Computer 1 :-192.168.0.1 logs in my previous mail). I have
disabled firewall settings on both nodes.  However, I still cannot get
it to work. I cannot access the shared folder of each node from the
other.  Is there something else I can try?
	
	p.s. There is a typo in my previous mail. I had opensm running
on computer 2 and not computer 1.
	
	regards,
	Ashwath

		Check your firewall settings on the 192.168.0.1 box.
Can you access the administrative share on each node from the other
(\\192.168.0.1\c$, and \\192.168.0.2\c$?)

		You probably have OpenSM running on this node, yes?  You
can't run osmtest on the same port where OpenSM is running.

		Don't know the details of this tool, maybe it's running
into the same problems as osmtest?  Try running OpenSM on the other node
and see if the problem follows the SM or not.
