Troubleshooting Service Console issues has always been a little bit annoying (well, at least to me 🙂 ). However, since ESX4 Update 2, there is a new command that will make your life a little bit easier. Login to your ESX server and take a look at #console-setup command.
As you can see, it is menu driven and extremely easy to use. Pressing 1, 2 or 3 will display information about vswif, NIC’s and vSwitch/DVS. Press 5 to configure the service console. Don’t forget to delete the old one first.
Proceed with 5.1 and fill in the required setting. Save your settings with 5.9 and exit with 6. And that’s it, you’re done! How cool is that?! 🙂
One more thing; do not use this command through a SSH session. You’ll lose the connection to your ESX host.
