cp only works with cooked files.

You need to do something like this:

dd if=/dev/vg01/rlvol2 bs=256k of=/dev/vg02/rlvol5

The destination raw device must be at least as large as the source. Man dd for details.

Moreover, to commands other than od or xd the raw device nodes will look just as they did before the dd (e.g. ls will tell you nothing -- other than a later modification time).
