Rename a volume group in HP-UX
Unmount all the file systems from the volume group
# umount /mount_point
Disable the volume group
# vgchange -a n /dev/vgName
Export a volume group whilst creating a map file and extracting VGID off the disks.
#vgexport -s -v -m /tmp/vgName.map vgName (-m Create map file, -v in verbose mode, -s vgid)
Recreate the volume group as described here.
NOTE: Since you have the VGID information in the map file you can skip some of the steps and proceed to the necessary step as decribed here
Import the volume group
# vgimport -s -v -m /tmp/vgName.map vgName
Activate the newly created volume group.
# vgchange -a y /dev/vgName
Assuming you have not touched /etc/fstab file, you can just run -
# mount -a (”mount -a” to mount all or use “mountall” or use individual mount point)
