>From the vgscan(8) man page:

*--mknodes* Also checks the LVM special files in /dev that are needed for
active logical volumes and creates any missing ones and removes unused ones
The years I have been working with lvm I have never had to use this
command.  Typically as long as I mark the volume group as active on the node
that I want the vgscan to be usable  vgchange -a y ${volume_group} takes
care of presenting the device files where on the node it was activated on.

Hope that helps.
