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

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

22 See lvm(8) for common options.

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

30 Scan devices for LVM physical volumes and volume groups and
