.SH NAME
vgscan \- scan all disks for volume groups and rebuild caches
.SH SYNOPSIS
.B vgscan
[\-d/\-\-debug] [\-h/\-?/\-\-help] [\-v/\-\-verbose]
.SH DESCRIPTION
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 \fBlvm.conf\fP(8) to restrict 
the scan to avoid a CD ROM, for example.
.LP
In LVM2, vgscans take place automatically; but you might still need to
run one explicitly after changing hardware or filters.
