[clue] networking Q? (SOLVED)

[CARL WAGNER]

Mike,

You may want to look at the file:
   /etc/udev/rules.d/70-persistent-net.rules
Or at least be aware of this file.  I have been burned by this when copying VMs and such.

(Solved).  Thank you.  I just needed a way to figure out which eth the network was on.

Think I might've figured it out.  Discovered ethtool -i will give you the driver of the device.  Discovered the 10G is actually eth4 on this box.   Testing my hypothesis.

Did you make sure the HWADDR is the same?  You can just comment that out too if you're using a single adapter.

OK, I'm running low on my bag of tricks,  as is my custom when I get desperate, I consult the council!

I have a series of seven DL380's using 10GB 2 port NICs which are HP 560 SFP adapters.  Using the same configuration on each host, I've been able to get network on six of them, using CentOS 6.7; config files follow

As near as I can tell, the only difference between the one without network, and the 6 that do, is the six that do have two of the 10GB nics, and the one without, has one.  (2 ports to each NIC)

Ethtool shows no link, ip link show, shows BROADCAST, MULTICAST, UP,  state unknown.

(scratches head)   If I'm missing something, I sure don't know what it is.  Got my networking guy to show me a copy of the switch port config, it's identical for all ports.  My onsite guy assures me it's plugged in and they've got link light on the cable.

If I'm missing something, it sure isn't jumping out at me.  So all advice is appreciated.
Is there a way to tell definitively which ethernet I need configure?  In case maybe it's not eth0?   Unlikely - since the other six came up fine when I configured eth0, but I'm running low on ideas.
