The currrent internal structure of LVM2 makes that difficult.
Add -vvvv to commands for more information like that.

Invalid devices are filtered out at a low level in the libraries
so tools such as 'pvcreate' never see them.

If your disk has a partition table, then LVM2 insists you use those
partitions to reduce the risk of accidents.

Did you try that?
(And then you might need to run 'vgscan'.)
