Hello Matthew,<br><div class="gmail_quote"><br>Thanks for replying, This I have alredy tried but I dont see and data <br>traffic on ib0 interface (visual indication is LED blinking), event I run Pallas<br>after boting mpd in the same way!<br>
<br>secondly on starting node (for mpd) mdptrace -l shows IP of ibnode1 and IP on node2 and vice versa for other node<br>
what is the reason?<div><div></div><div class="Wj3C7c"><br><br><div class="gmail_quote">On Mon, Apr 7, 2008 at 10:29 PM, Matthew Koop <<a href="mailto:koop@cse.ohio-state.edu" target="_blank">koop@cse.ohio-state.edu</a>> wrote:<br>

Devesh,<br>
<br>
In addition to specifying ibnode1 and ibnode2 in the mpd.hosts, can you<br>
add --ifhn=ibnode1 to the mpdboot command (assuming you are starting<br>
mpdboot on ibnode1).<br>
<br>
mpdboot -n 2 --ifhn=ibnode1<br>
<br>
Let us know if this helps. Thanks.<br>
<br>
Matt<br>
