Updated NIC now I can't connect to vSphere

I have a system with ESXi installed 5.x, I made changes to NICs because for some reason they were only running in half duplex mode for some reason any. The card has been set to Auto and I forced it 100 Full and then I lost the connection to vSphere. I now can not connect to vSphere because it was networking... What can I do now? Im not too experienced with ESXi so Im at a loss.

TIA

Hi AmDD,

Great that you have access KVM! You can do the following to get management on your ESXi rogue server:

  1. Press and then logon with 'Root' and password
  2. Select Troubleshooting Options in the customization of the system screen
  3. Press to enable the ESXi environment so that it displays ESXi Shell is selected in the right pane
  4. Press to the local shell
  5. 'Root' login and password

At this point, you should have a shell with ~ # on the screen and a cursor blinking on ready for the entry. If this is the case then continue

  1. Run network vswitch standard list esxcli (assumes that you use a standard vSwitch and not a distributed vSwitch)
  2. Note uplink associated with this vSwitch (read the physical network adapters)
  3. Run network nic set-n vmnic5 - esxcli has
  4. Repeat for all the vmnic related delinquency vSwitch

Once you have confirmed you have taken over the management of the perpetrator, then you can store as follows:

  1. Press to return to the DCUI
  2. Follow steps 1-3 in the first section, but make sure that esxi Shell is disabled
  3. Press can again to disconnect from the DCUI
  4. Grab a cold beverage of your choice and sit back to relax

Note: This is not strictly necessary but does not remove the fingerprints

Let us know if it works!
