HostNetworkSystem.UpdateNetworkConfig fail

Ever get this error when you try to migrate a standard switch vmkernel port to a DvS?

"Call "HostNetworkSystem.UpdateNetworkConfig" for object "networkSystem-64" on vCenter Server "vCenter.company.com" failed."

It is most likly because the SvS is being used by something. In my case, it was the "Core Dump" feature utilizing the SvS. From the command line, run this to check the configuration: "esxcli system coredump network get". If you get a configuration that is "true", you will need to disable this for now. To issue the disable command: "esxcli system coredump network set –enable false". Check the config again by typing: "esxcli system coredump network get". you should now see the status as "false". Now migrate your interface to the DvS. Once it has been moved, re-enable Core Dump by typing "esxcli system coredump network set –interface-name vmk0 –server-ipv4 10.x.x.x –server-port 6500". Of course the 10.x.x.x should be the vcenter ip and check to make sure what port you are using from your original get command. After this, issue the "esxcli system coredump network get" command one more time to make sure the configuration matches from the previous configuration on the SvS.
