pvcreate by /Dev/SD? Or by uuid?

Recommended way to pvcreate please and if you can give me the URL to the documentation?

pvcreate /dev/sd?

Or pvcreate -u once blockid or other commands give the uuid?

Never mind.....
Another forum - user says man pvcreate and in the man page example it specifically says pvcreate /dev/xxx.

Seems -u is maybe only used in recovery or other restoration operations.

Thank you.
