man gmultipath is your friend ;)
This is an active/passive multiple path architecture with no device
knowledge or presumptions other than size matching built in. Therefore
the user must exercise some care in selecting providers that do indeed
represent multiple paths to the same underlying disk device. The
for this is that there are several criteria across multiple underlying
transport types that can indicate identity, but in all respects such
identity can rarely be considered definitive.
