<div dir="ltr"><br><div>OK, I'm running low on my bag of tricks, as is my custom when I get desperate, I consult the council!</div><div><br></div><div>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</div><div><br></div><div>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)</div><div><br></div><div>Ethtool shows no link, ip link show, shows BROADCAST, MULTICAST, UP, state unknown.</div><div><br></div><div>(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.</div><div><br></div><div>If I'm missing something, it sure isn't jumping out at me. So all advice is appreciated.</div><div>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.</div><div><br></div><div>Mike B</div><div><br></div><div>(etc/hosts)</div><div><div>127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4</div><div>::1 localhost localhost.localdomain localhost6 localhost6.localdomain6</div><div>127.0.1.1<span class="" style="white-space:pre"> (HOSTNAME)</span></div></div><div><span class="" style="white-space:pre"><br></span></div><div><span class="" style="white-space:pre">(/etc/resolv.conf)</span></div><div><span class=""><span style="white-space:pre">search DOMAIN1 DOMAIN2
