<p>I have an infiniband network up and running between two linux boxes through a switch. But when I reboot the system on which the subnet manager is running, the lights on the switch turn orange. Running 'ibdiagnet' on the box with subnet manger showed me the
following error.</p>

<p>Running opensm or restarting opensm service fixes this, but I am unable to understand why I am having this problem in the first place and restarting the opensm service after every reboot is obviously not a practical solution. Can some one please point me
in the right direction as to what the issue might be here.</p>
