Well yes you can!!! Follow the below and that's it to change vg and lv as well..

Export the VG:

1. # umount /oldmountpoint
2. # vgchange –a n vgname
3. # vgexport –s –v –m /etc/lvmconf/vgname.map vgname

Rename the VG directory, edit LV names, and re-import:

1. # mkdir /dev/newvgname
2. # mknod /dev/newvgname/group c 64 0x010000 (Minor number example. Please ensure that it's unique)
3. # cp /etc/lvmconf/vgname.map /etc/lvmconf/newvgname.map
=>If you want to change your logical volume names, simply use the vi editor to modify the names in the map file.
4. # vi /etc/lvmconf/newvgname.map
VGID 0a0a0a0a0
1 newlvname

5. # vgimport –s –v –m /etc/lvmconf/newvgname.map newvgname
6. # vgchange –a y newvgname
7. # vgcfgbackup newvgname
8. # mv /oldmountpoint /newmountpoint
9. # vi /etc/fstab => add entry
10. # mount -a

-You're done!

Please let us know if you find any issues!

NAME
vgcfgbackup - backup volume group descriptor area SYNOPSIS
vgcfgbackup [-d|--debug] [-h|--help] [-v|--verbose] [VolumeGroupName...] DESCRIPTION
vgcfgbackup allows you to backup the metadata or Volume Group Descriptor Area (VGDA) of one to all volume groups to files in /etc/lvmconf. If you don't give any volume groups in the command line, all of them will be backed up. This DOESN'T backup user/system data in logical volume(s)! To restore volume group descriptor area backups see the vgcfgrestore(8) tool. A 10 step history is backed up in /etc/lvm- conf/VolumeGroupName.conf and /etc/lvmconf/VolumeGroupName.conf.[1-9].old. This enables you to restore your volume group configuration up to 10 steps back in the backup history. OPTIONS -d, --debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about vgcfgbackup's activities. DIAGNOSTICS
vgcfgbackup returns an exit code of 0 for success and > 0 for error: 1 error doing backup 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line SEE ALSO
