3.4.7.11 Mount Point Change
When the server detects that a volume's mount point has changed, for each callback object that is registered in the list of callback objects, the server MUST call the callback object's IVdsAdviseSink::OnNotify() (section 3.3.4.3.1) method by using a VDS_NOTIFICATION (section 2.2.1.3.9) structure that has the following attributes:
objectType member is VDS_NTT_MOUNT_POINT.
MountPoint member is a VDS_MOUNT_POINT_NOTIFICATION (section 2.2.1.3.8) with the following attributes:
ulEvent is VDS_NF_MOUNT_POINTS_CHANGE.
volumeId is the VDS_OBJECT_ID (section 2.2.1.1.3) of the volume object whose mount point was changed.
