.SH DESCRIPTION
.B vgchange
allows you to change the attributes of one or more volume groups.
Its main purpose is to activate and deactivate
.IR VolumeGroupName ,
or all volume groups if none is specified. Only active volume groups
are subject to changes and allow access to their logical volumes.

.B vgchange
recognizes snapshot logical volumes which were dropped because they ran
out of space, it displays a message informing the administrator that such
snapshots should be removed (see
.BR lvremove (8)).
