<p class="MsoNormal">Not sure if this is where I can get help with this, but...<br>
<br>
Running standard CentOS 6.7<br>
Mellanox infiniband adapters<br>
Running OpenSM on one node<br>
<br>
If that node reboots, suddenly it can no longer ping/be pinged across the ipoib network.<br>
It can ping itself and it can ping any boxes that get rebooted.<br>
Until they are rebooted, those boxes can ping each other but NOT any node that has been rebooted.<br>
<br>
Almost like there is a new network and you have to reboot to join it...<br>
<br>
Grrr...<br>
ibhosts still shows all hosts. I can also ibping any node just fine. It is just the IPOIB bit that seems to choke.<o:p></o:p></p>
