This option is now ignored. Instead, use \fBlvs\fP(8) or
\fBlvdisplay\fP(8) to obtain the device number.

Applicable only when \fBlvmetad\fP(8) is in use (see also \fBlvm.conf\fP(5),
global/use_lvmetad). This command issues a rescan of physical volume labels and
metadata areas of all PVs that the logical volume uses. In particular, this can
be used when a RAID logical volume becomes degraded, to update information
about physical volume availability. This is only necessary if the logical
volume is \fBnot\fP being monitored by dmeventd (see \fBlvchange\fP(8), option
\fB\-\-monitor\fP).
