All partitions starting with sda (sda1, sda2, ..., sdan
) will be on the first disk, all partitions starting with sdb on the second, and so on.
This is different for volume groups, they belong to a LVM setup. For example, a volume group can reside on a single partition on a single physical disk, but you can also have volume groups that spend over several partitions on one (or more) disk(s). To get reliable information on that you will have to use the tools LVM offers, like pvdisplay, vgdisplay, lvdisplay, ... .
