The "port_rcv_errors" attribute on OpenSM side of SM link is 65535, other
errors attributes are all 0. How can I check SM link status on the switch
side? Is there anything I can do if the SM link port on the switch side is
not in init state?
I don't think it's cable issue. I have 3 unmanaged switches on different
system, all have the same problem.
Thanks!

What do the port counters say on both sides of the SM link ?
Maybe try different cables on the SM link and see if this gets better.
