Rename Root Logical Volume group?

Hello,

I'm running Ubuntu 12.04. I need to rename my root logical volume group and it's bootmanager/fstab accordingly.

Here is the output: I need to change the HP-TEST001 to PRODGROUP01. Please advice me.

Code:

root@PROD-02:/home# vgdisplay

Alloc PE / Size 2498 / 9.76 GiB

# that works even if disks are added and removed. See fstab(5).
