As you seem not interested in useful volume group and volume names (currently your vg is named
VolGroup00 and your lv
LogVol01), I'll leave these untouched.
So the only need is to change the mount point, so you edit
/etc/fstab and change the respective line from
oracle. That is for the next reboot.
mkdir /u001/app/oracle # necessary before changes can take effect!
umount /u001/app/pracle # unmount the old one
mount /u001/app/oracle # mount it on the new place
rmdir /u001/app/pracle # and dispose of the garbage.
for cleaning up and for having the changes immediately.
On the long run, it might be useful to at least have useful volume names: that's what
lvrename is for. You would do that with
lvrename VolGroup00/LogVol01 oracle
after which an edit of the fstab is necessary again, as the device location changes from
/dev/VolGroup00/oracle resp. from
