kickstart issue

Im trying to automatize vsphere installation to SD cards (Lenovo server).

I have used this guide to create my kickstart - vSphere Documentation Center  where I understood I could use following formats:

install --firstdisk=ESXSD (where ESXSD is my SD raid name)

or

install --disk=mpx.vmhba1:C0:T0:L0

however none of this works. The installer will always throw red error (which I dont know how to catch) and then it ends up with standard installation prompt (ignoring kickstart accepteula etc).

Thanks for help
