If its mounted you'll need to unmount it before you can deactivate it, and if
its in use you wont be able to unmount it....
I'm guessing that with a name like VolGroup00/LogVol00 its probably the root
filesystem so probably the best procedure is to boot from your live CD, then
umount /dev/VolGroup00/LogVol00
and you should then be able to deactivate it then do your lvrename/vgrename
stuff
You'll also need to change any entry it may have in /etc/fstab before you reboot
back onto the internal disks, or it wont mount on bootup and if its the root
filesystem thats pretty fatal!
