How to add an extra network card to ESX Server 3

Hi There

I would like to get an existing VMware ESX 3 srever to recognise a new network card that I've recently added.

I initially installed an ESX server with 2 network cards but I've recently added a 3rd but I can't seem to see the new card in Virtual Center.

Any advice would be appreciated.

Thanks

Regards

What kind of network card is it?

Is it on the IO compatibility guide?

http://www.vmware.com/pdf/vi3_io_guide.pdf

If it's on the list, the VMkernel will automatically load the driver...and you should see it in Virtual Center.

Hello,

Another thing to realize is that if you moved around cards to add in the new one, the ESX server may have a different opinion about what is where than you do.

While it should fix this up itself, you may have to do so.... Did you move around PCI cards to add the new one?

If you login to the SC and run 'lspci' do you see the device? If you report that output we perhaps can assist.

Also, run 'esxcfg-nics -l'. Do you see your NIC card there?

Best regards,

Edward

Hi There

I used the command to check the network cards installed on the ESx servers and I can only see the orginal 2 network cards in the configuration.

Should the ESX server automatically pick up the new card which I installed?

Thanks

Hello,

Yes, the new card should be seen if it is a supported card. Did you reboot the server or try to use plug-n-play? Can you dump to the forum the output of lspci? Can you boot your ESX server in Troubleshooting mode and also post its output for lspci?

This will aid us in debugging the problem.

What is the type of NIC you added to your system? Make and model?

Best regards,

Edward

Is your card supported on the HCL? There is at least one ESX patch that may help your issue.

I heard that you have to run kudzu to cinfigure the hardware at Linux level (OS). kudzu will use the /etc/sysconfig/hwconf file.

After you run kudzu, reboot your ESX server.

Hello,

Unfortunately kudzu runs AFTER the vmkernel loads and the new NIC has to appear inside the vmkernel in order for kudzu to see it. Things that work normally inside Linux are not quite the same on ESX as the SC is in reality a virtual machine and only sees what the vmkernel lets it see. However, lspci still shows all the hardware. That is the important command to run before tackling the problem. And yes Kudzu will see a device if lspci also sees the device, however a reboot is not needed.

When a NIC does not appear, generally it is just not on the HCL and there is no driver for it. Or the hardware ID is an issue as mentioned previously.

Best regards,

Edward

Yes this should be automatically!

Power off ESX host, put in the new Card, power On ESX host and you should have new vmnics visible in your vcenter GUI!

Like the others have asked, what is the make/model of the NIC?

I had this issue using an HP ProLiant BL680c G5 blade when add a mezzanine card NC373m Dual Port Multifunction 1Gb NIC.

After I have run kudzu and esx reboot then the issue was fixed.

I was able to get 3 NICs on my machine 2 of which are the intel pro's and one onboard realtek, however I was having some Hardware failure restarts. It was working for a while then just started restarting. I noticed when the ESXi drivers were loading that it again failed while loading E1000 driver (Intel Pro 1000 G/T). The hardware ID's are identical except for the IRQ's. Am i missing something? I know the realtek works, have tested extensively before adding the two Intel's

Any Suggestions?

Thanks,
Joey
