The vgrename command is used to rename the name of a volume group in Linux. This command is useful when you want to change the name of a volume group to something more descriptive or to follow a specific naming convention.
Overview
The syntax of the vgrename command is as follows:
vgrename [OPTIONS] OLD_VG_NAME NEW_VG_NAME
In this syntax, OLD_VG_NAME is the current name of the volume group that you want to rename, and NEW_VG_NAME is the new name that you want to assign to the volume group.
Here is an example of how to use the vgrename command:
vgrename vg01 myvg
This command renames the volume group vg01 to myvg.
