Hello,

 

I replaced a NIC in my server as the existing one appeared to have gone bad. Since doing so, I've been unable to connect to my server. I have tried the following:

• Deleted the network-rules.cfg and network.cfg files (multiple times)
• Tried 3 different NIC cards, including regular PCIE cards and daughter cards.
• Reinstalled unraid on the flash drive and copied over the backed up config folder.
• Place server on a different network/switch/dhcp server to confirm no issues that way.

 

I have attached a diagnostic log so that hopefully you can offer some assistance here. Server is a Dell R720XD.

 

TIA

The NIC is not giving any info,not even link speed:

 

Settings for eth0:
    Supported ports: [  ]
    Supported link modes:   Not reported
    Supported pause frame use: No
    Supports auto-negotiation: No
    Supported FEC modes: Not reported
    Advertised link modes:  Not reported
    Advertised pause frame use: No
    Advertised auto-negotiation: No
    Advertised FEC modes: Not reported
    Speed: Unknown!
    Duplex: Half

 

Are the other one you tried same or a different model?

 

I've tried:

• Two daughter cards of the same model (Dell card with 2xSFP+ & two GBE ports)
• One daughter card with two 10GBE ports & two GBE ports.
• One PCI intel card with two SFP+ ports.
• One daughter card with four GBE ports

All five cards yield same result. Note that when I swapped cards, network-rules.cfg and network.cfg were deleted and server rebooted each time.

 

Thanks.

Please post new diags with a different NIC, Intel if possible.

I will have to try that later when I get home from work. Should I remove the daughter card when I install the intel PCIE card?

Light bulb moment, pretty sure the issue is the IPMI NIC being set as the main one, I remember other Dell users with the same issue, IIRC you can disable that in the BIOS

Are you referring to the one for IDRAC? If so, that one has been disabled as I saw that as ETH0 in one of the .cfg files during my troubleshooting.

driver: cdc_ether
version: 6.1.106-Unraid
firmware-version: CDC Ethernet Device
expansion-rom-version: 
bus-info: usb-0000:00:1a.0-1.6.3

 

Pretty sure eth0 is the iDRAC NIC, it's USB.

See this post:

Well damn, I did disable it so I'm not sure why it's still trying to grab that as the primary NIC. It's actually disabled altogether, not just the passthrough...

I'll confirm when I get home later.

Seems about right, "Dell Computer Corp. iDRAC Virtual NIC" is listed under usb. Also interesting is the lack of any pcie network card listed in the diagnostic. 

Which is odd, because when I performed the diagnostic via console this morning, the four-port 2x10GBE/2x1GBE NIC was/is definitely installed.

 

Actually, that's interesting too. If Unraid was picking up the USB/IDRAC port, it was only showing three of the four ports on the other 3 NICs. Can unraid only pickup four ports total?

Ok. So I...:

• ...installed one of the intel daughter cards, actually, they're all intel. I opted for the dual SFP+ card,
• booted up the server and disabled each setting (passthrough, and the physical port itself) pertaining to IDRAC and the associated integrated port,
• booted into unraid, noticed that ETH0 was "missing", resulting in IPV4 address being "not set".
• Renamed the network.cfg file to network.cfg.old and rebooted.
• Same result - IPV4 address not set.
• Pulled a diagnostic log (see attached).

Any ideas here on what I should do next?

 

Thanks again,

Z

The USB NIC is gone, which is good news, but no other NIC is being detected, try a different PCIe port or a different NIC.

I ended up removing the daughter card and using a standard PCIe NIC (Intel dual SFP+) and got her up and running again. IDK if the daughter card port is bad or what but four different cards in it would not work.

 

Thank you for your assistance here.
