Redhat 6.5 NIC does not seem to be present

This used to work - now all of sudden we get this error when we try to "up" this NIC em1

device em1 does not seem to be present, delaying initialization -  [FAILED]

Redhat 6.5 with latest updates - the NIC is fine - we suspect a configuration error

What should we check? we checked the ifcfg file and compared it to other scripts of other nics that it looks ok

Hello,

to get to the bottom of this, please paste here the output of these commands as well as the init script from this network:

lsmod
lspci
/etc/sysconfig/network-scripts/ifconfig-eth[?]

also, it would be helpful to paste some lines of dmesg relating to the adapter (when you try to 'up' the interface).

Also, you can try adding the interface (if it is presend) by deleing the ifconfig file and run system-config-network-tui:
# system-config-network-tui

Hello,

from what I can see you have two quad port ethernet NIC:
Intel Corporation I350, using the loaded module igb.

one of them onboard, the other being a PCIe card (the p* ifs).
I this about right or did I miss something?

So you already checked the switch login of port 2 of the first (internal) NIC?
0
 
Mohamed HammadAuthor Commented:
You are right

 I don't get the question about the switch login - this setup used to work - some how we managed to get to the current state - not sure how - we know the card and the port are functioning "hardware wise"

MazdajaiCommented:
Are you sure the bonding is p2p1 and p2p4 rather than p2p1 and em1?
0
 
Mohamed HammadAuthor Commented:
It is em1 and p2p1

of course as em1 is "not found" the bond works only on p2p1

'we know the card and the port are functioning'

Curious...What method have you done to check all ports are functional? Have you test the card in another server or start it in the pre-boot environment?

ethtool em3
ethtool em4

Mohamed HammadAuthor Commented:
We know the card is working because it stopped working after we tried to do the bond - and because it shows link status up in the out of band controller card during boot until the OS takes over.

Thanks for your time and help.

Ww were out of time on this - we solved the issue by re installing Red Hat on the server

If it is the case I assume the nic driver were broken during the kernel update. If it happens again you can try booting the backup kernel via the splash screen.

This would be a helpful piece of information if it is included on the first post.

>>We know the card is working because it stopped working after we tried to do the bond - and because it shows link status up in the out of band controller card during boot until the OS takes over.

Got it

would a broken nic driver affect only one port in a nic?

Is there a way to give the points without marking a specific reply as a solution?

Since it broke after a kernel update and worked after a rebuild, it is an indication of a driver issue. I just updated few RHEL 6 box with bonding (mode 0) 2 weeks ago but havn't see any of this issue. It is possible because em3/4 was NOT in bond mode and they are visible to the OS, while em0/1 are gone.

Currently active devices:
lo p2p1 em3 em4 p2p2 p2p3 p2p4 bond0

I suggest mark #39964027 (yours) as solution and other threads as assisted if you think it is appropriate?
