How to get the mapping from VMDK file to the physical disk

Hi,

I'm new in this area. Maybe someone already posted the similar question. We want to get a mapping between the VMDK files and the physical disk.

I can open the vmx file and get the content. But it only gives me the logical location, such as /vmfs/volumes/storage1/TestVM1/TestVM1.vmdk. But how do I know which physical hard disk this vmdk file is located? For example, /dev/sda or /dev/sdb.

Thanks.
