NOTE: Volume name is represented by the Volume GUID. Volume path is the drive letter or the mount point directory where that volume is mounted.

There it says to use this PowerShell script:
Get-WmiObject -class Win32_Volume -computername localhost | where-object {$_.name -like "\\?\*"} | select-object label, name, capacity, freespace | format-list

In a program you should call ClusterPrepareSharedVolumeForBackup function.
