1. Determine the UUID for the volume group that you want to rename:

# vgs -o +vg_uuid
WARNING: Duplicate VG name testvg2: Existing OEsLyZ-ueap-D66F-6LEB-BKqC-A5B1-exlfZ5 (created here) takes precedence over q7jsuu-f3f8-mVVu-HpMm-FXdK-Xe3Y-d2nVfU

Note: For additional steps to help determine which UUID to operate on, see the Diagnostic Steps above below.

2. Once you have the UUID you can then rename the Volume Group using vgrename:

# vgrename q7jsuu-f3f8-mVVu-HpMm-FXdK-Xe3Y-d2nVfU testvg

Volume group "testvg2" successfully renamed to "testvg"

3. Activate the new Volume Group.

# vgchange -ay testvg
1 logical volume(s) in volume group "testvg" now active

4. Verify the Volume Group.

# vgs -o +vg_uuid
