       vgscan - scan all disks for volume groups and rebuild caches

       vgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes]
       [-P|--partial] [-v|--verbose]

       vgscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of
       other disk devices in the system looking for LVM physical volumes and
       volume groups.  Define a filter in lvm.conf(5) to restrict the scan to
       avoid a CD ROM, for example.

       In LVM2, vgscans take place automatically; but you might still need to
       run one explicitly after changing hardware.

       See lvm for common options.

              Also checks the LVM special files in /dev that are needed for
              active logical volumes and creates any missing ones and removes
              unused ones.
