Use 'dd' to copy block device to block device. (The name reminds me of DDR
every time I use it!)

Is there a maximum edev size?
You can copy the LUNs with DDR, but you have to first define an EDEVICE for
them.

OK, I want to make sure I am understanding it clearly. Its an interesting
idea, but I really can't afford to blow away the original disks, so want to be
really sure.
The existing disks are used by the virtual machine by having LOADDEV statements

What I mean is:
define them even temporarily as EDEVs

define them even temporarily as EDEVs for the DDR and go for it.

If they're defined as EDEVs then you can use DDR.
FBA (EDEV or 3370, etc al) being fixed block, copying the whole disk will
include the boot partition. (Partition tables are not really needed on
fixed block disks, even laptop SSDs, but don't get me started.) Any
"partition table", and all
I have a few RHEL servers that run on z/VM but boot off of a direct attached
