[ofw] Setting up Infiniband over WinXp- Help Needed

[Leonid Keller]

Hi Ashwath,
 
If you still have problems, send us, please, the output of 'vstat -v'
and 'ipconfig /all' on both machines.
 
TIA
Leonid

	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.
