[Users] Error : Missing master SM in the discover fabric

[Kenja, Krishna (kenjakt)]

Hello,


I do have opensm enabled at boot. I can see that opensm running when I run 'service opensm status', but there is orange light on the switch and I have to restart opensm to get it to green/working.

IB and OPA Fabrics must have an SM to configure the fabric.

I suggest enabling opensm at boot.

systemctl enable opensm

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.


-I---------------------------------------------------
-I- Bad Fabric SM Info
-I---------------------------------------------------
-E- Missing master SM in the discover fabric


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.



Thanks
Krishna
