vgchange: Change the activation status of logical volumes in the specified volume group (determine with `vgscan`).

vgchange

$ sudo vgchange --activate ${select} ${volume_group}}

try on your machine

This command is used to activate the specified volume group on a Linux system. Here is a breakdown of the command and its components:

sudo: This is the command used to execute another command with administrative privileges. It allows the user to run the subsequent command as a superuser or root.
vgchange: This is the command that is used to change the attributes or states of a volume group. In this case, it will activate the specified volume group.
--activate: This option is used to specify that the command should activate the volume group. It tells vgchange to bring the volume group into an active state.
${select}: This is a placeholder variable that should be replaced with the actual name of the volume group you want to activate. It represents the volume group that you want to make active.
${volume_group}: This is another placeholder variable that should be replaced with the name of the volume group you want to activate. It represents the name of the volume group you want to make active.

To use this command, you need to replace ${select} with the actual name of the volume group you want to activate and ${volume_group} with the specific name of the volume group you wish to make active. Then, execute the command using sudo to run it with administrative privileges.
