vgchange - Modify Volume Group Settings

The vgchange command is a part of the Logical Volume Manager (LVM) toolset and is used to change the settings of an LVM Volume Group (VG). This command can only be executed by the superuser (root) because it involves managing system-level storage configuration.

The basic syntax for the vgchange command is as follows:
vgchange [OPTIONS] VOLUME_GROUP_NAME。

Here, "VOLUME_GROUP_NAME" is the name of the volume group you want to modify.

Some commonly used options for the vgchange command include:

-a y VOLUME_GROUP_NAME : Activate (enable) the specified volume group.
-ay : Activate (enable) all volume groups.
-a n Deactivate (disable) the specified volume group.
-an : Deactivate (disable) all volume groups.。

# vgchange -a n myVG ←Deactivate the volume group "myVG"
# vgchange -ay ←Activate all volume groups.
