[ofa-general] GPFS node loses IB-connection

[Scott Weitzenkamp (sweitzen)]

Yes, you can tune it.  Here's an example via the switch CLI:
 
SFS-7000D(config)# ib sm subnet-prefix fe:80:00:00:00:00:00:00
node-timeout <value>

The default is 10 seconds, it can be configured up to 2000 seconds.  If
a HCA is completely unresponsive for longer than the node-timeout value,
then we consider that HCA out of service.

	Koen,
	
	So it is most likely you hit the same bug as 229 (Scott pointed
out earlier). The same workaround might work for you by renicing ib_mad
as Scott suggested.
	
	I think this should be a SM query timeout tunable value in Cisco
SM. Am I right, Scott?
	
	Thanks
