A couple of "interesting" aspects of this "boot from the USB" idea....
The z10, which is where the "boot from DVD" is supported, comes with a HMC
that has both the DVD and a couple of USB ports. USB is supported as an
inport/export device for configuration files. The HMC runs Linux and Linux
treats the DVD and USB in a very similar manner (from the user
perspective). So "conceptually"(!) it should be a relatively simple move
from booting from DVD to booting from USB. With 16, 32, and even 64 GB USB
flash drives these days, there are all kinds of possibilities for having
very portable systems.

I am voting for the USB D/R tool.
What type of requirement do we have to create?

I am liking the USB port idea even more. How cool would it be to walk
into a D/R site with just a couple of thumb drives in your pocket to
restore your whole z/VM system?

I know what you said. :-) The procedure for building a DVD image
includes tools that you don't have, so you would then ask for the tools.
But the procedure and tools have value. And down the rabbit hole we
go.... I KNOW how this story ends. :-)
Maybe the good Dr. Boyes could write up and submit the requirement to
WAVV....?
You could, but I would like to gently suggest that it isn't going to
happen. If you want to be able to have a system that is recoverable
from
the DVD drive, then that is the requirement to levy. And since it is a
function of backup/DR, it properly belongs to the backup products.
But keep in mind that its all part and parcel of the larger requirement
to
get z/VM to support storage devices other than SCSI disk, ECKD, FBA, and
3590 tape.
