Hi,
A physical disk is a single disk... a physical volume is what defines a group of physical disks ( it can be only one disk, but you can add more ), like in a RAID device...
The lspv will show you information about a physical volume on a volume group ( a volume group can be anything [ we're talking sbout disks ] that is grouped to look like one ).
It's not difficult, just learn the right terms...
