Hi,

I was just trying to get a VM on a vlan and configured a new vSwitch for that.

I made the mistake to attach the main network adapter to the new vSwitch, what probely switches the default adapter to the new vSwitch in stead of the old. The old vSwitch has the vmKernel for accessing ESXi.

I did have a 2nd network adapter for the storage network which was on the same physical network, but on a other subnet, but this host doesn't have the VMkernel i think... (thats what i am gonna try now)

What can i do to get it started again? i am now at home working remote, tomorrow morning i can get behind the service console to solve the problem.

thnx in advance!

Regards,
Rick

In total how many NICs do you have on the Server ?

On what model of Server (IBM, HP or Dell) is the ESXi installed ?

By default, vSwitch0 is allocated to the Service Console.

There where two Nics on a Dell 2950.

I just solved the problem (i am now back at work) by entering the Service Console and going to the Management Interface.

After reselecting which physical network interface the mngt interface should should work with, nic0 was reassigned to vSwitch0 and all attached Virtual Machines started working again automatically (also attached to vSwitch0).
i accedently


Other options i thought i would have, would be, to get between nic1 and the storage array, but then the vmkernel had to be assigned to that nic also... (also possible with the service console)

The prepare myself today, i also found this url that may help others...

You can reconfigure a vSwitch by using cmds in the unsupported mode in ESXi.

Thnx for your help!

ps. i could have fixed this remote, but i didn't have a Dell DRAC card installed so i can take over the console screen with vnc. I can tell u this, that's gonna change soon! ;-)
Then i can also check the hardware status by snmp/smtp..

Regards,
Rick
