So the OpenSM was up and running and these messages appeared in the log.
Did anything change in the subnet ?

These are failures of the OpenSM to send a SM Get(NodeInfo) which are
used during the periodic subnet sweeps. I think the only way this error
happens is if physical link is not present on the local link (e.g.
logical link is not in init state or beyond). 

So was a cable pulled somewhere ? 

Is this problem intermittent ? Does it come and go for no apparent
reason ? Does the subnet get out of this state or do you need to 
restart OpenSM ?

Are there any other messages in the log around this which might be
useful ? 

Thanks.
