>/dev/sdd indeed has no partitions, the whole drive is a LUKS container.
My best suggestion is to create a maximal primary partition as /dev/sdd1
and use that as your LUKS volume. That way, LVM will receive the
partition details from udev and *might* not bother re-reading the
partition table (but don't bet big bucks on it).
