Interface Ethernet Port 0 is down. Check cable! Error

[Canes]

Hi,

 

Getting the error in subject line.  Tried following steps I found in a few other posts on this matter (some not applicable to me since not using NIC card) and haven't had any luck yet.  It started earlier today after I swapped out 2x1TB cache drives I had in pool for a single 2TB cache drive to get extra storage. Since the first time booting back up after that I can only boot into GUI with monitor directly connected to server but not into webGUI.  Diagnostics file attached.  What is really weirding me out is that nothing should've shorted (no power surges, etc.) between me properly stopping array shutting down, following these steps to swap the cache drives around and now I don't even get a light on my motherboard's ethernet port telling me any of the different cables I tried are even connected.  Tried both ports on motherboard's I/O panel with same result and it was literally working fine until I swapped cache drives out and consolidated the two to the single drive.

 

Running v6.9.2 - hardware specs in signature. Any help would be greatly appreciated.  If not for fact I've spent last week just loading data onto this brand new server I would start over but really do not want to try and start from scratch losing that time.  I also saw from other posts from people who tried this to fix problem and didn't work.

 

Posts/Steps I've tried to date:

1. Renaming /config/network.cfg on flash drive to different file name and booting back up server but this did not do anything that I could tell.
2. Put original file back to /config/network.cfg since nothing happened and no other file was recreated as I thought might happen from previous step and using text editor on another computer I updated text in network.cfg file to say below. Now it shows 192.168.1.23 in the top right corner on direct GUI like it should but it is not actually connected.  Seems like this fix only forced it to display what should be the right IP address for me.

Adding Diagnostic File

No link detected on eth0:

 

Link detected: no

Does this mean the motherboard ethernet port has failed if neither are lighting up even?  I can still try and return the motherboard as defective if that is the case.

Try another cable and/or switch port, if still no link it's likely the NIC.

I have tried multiple cables and different ports on switch (Orbi RBS850 satellite that was working fine). Does this mean anything that eth0 says Link detected: yes in the /system/ethtool.txt file?  What file are you referencing so I can try and learn too.

 

**Mistakenly pulled this from different diags file taken prior to issue developing**

context to what i quoted from a different diags file

Yes, on the previous diags it said no.

Sorry - just realized I pulled a different (older) diagnostics file from when I was trying to diagnose a flash device error and networking was working fine then. Mixed up the two.

 

That is the file to look at though in the diags to see if shows link connected?

 

I went ahead and ordered a different motherboard from Amazon Prime that should arrive Sunday. Sucks I'll have to rebuild but I guess it is what it is when dealing with defective motherboard if we think NIC is issue.  Going to ship the old one back to Newegg this weekend and works out nicely they give you free return label for defective products.

Yep, and if it's showing link up that's not the problem.
