Re: vmkernel listed as disabled

Can you try a delete operation or using the --dvs-name and --dvport-id parameter?

I.e. run esxcfg-vmknic -e vmk1 --dvs-name MyDVS --dvport-id 511

Maybe you need to specify the --portgroup parameter with the dvPortgroup name your vmk is connected to too/instead.

--dvport-id
    -v
          Setting DVPort ID of the connection point (valid for vSphere 4.0 and later). Requires --dvs-name parameter.
   --dvs-name
    -s
          Setting DVSwitch name of the connection point (valid for vSphere 4.0 and later). Requires --dvport-id parameter
--portgroup
    -p
          Setting portgroup as connection point
