[fm-discuss] help locating problems...

[Tim Haley]

What you're seeing is that we believe there is a fault in a network
controller.  You should have also seen a console message with the case
number (35fc7dee-e5b9-6028-d333-cbcd5a272c35) and the message id
(PCI-8000-7J).  If you go the URL http://www.sun.com/msg and type in
the message id, PCI-8000-7J you should be taken to a knowledge article
describing this problem in a little more detail.

The faulty NIC is apparently on the motherboard (MB), that's
the FRU that would have to be replaced to fix the problem.

You can use the case number to dig out a little more information,

fmdump -V -u 35fc7dee-e5b9-6028-d333-cbcd5a272c35

should show you what ereports our diagnosis algorithm led us to believe
the device was faulty.
