No, they don't.
What does the local LDDS value say after reset ? Any way to get the

It fails too. Both ports go to DOWN after disable is issued and never come

Does HCA provide any internal route for local DMA so that local data

true?

Hi Folks,
I use opensm with a single unmanaged switch to connect several HCAs. I
found that HCAs take much longer time to get LID after opensm restart
without power cycle the switch. If the switch is power off/on before
opensm restart, then HCAs get their LIDs sooner. I'm wondering if there's
if there's
minhop table pre-existing in the switch which will prevent HCAs from
regain their LIDs soon. Is there any option to reset the switch during
opensm start?
Thanks!

Hi Hal,
I have a question regarding to this issue.
If I have both opensm and Cisco managed switch running in the same subnet,
can opensm automatically detect the Master SM and set itself as the slave
SM? Or I have to manually disable the SM in the Cisco switch in order for
the opensm acts
subnets. It shouldn't be the
case if there's only a single switch in a single subnet. Correct?
