What version of lvm?   (Run 'lvm version')

Looks like a bug: the vgmerge code checks for duplicate LV names 
but not duplicate UUIDs.

Is this still lvm1 metadata? (You didn't run 'vgconvert')

You're going to have to edit the UUIDs by hand:
  vgchange -an oradata1_a
  vgcfgbackup oradata1_a
Edit the UUIDs in /etc/lvm/backup/oradata1_a uuid making them all
different:

                lvol1 {
                        id = "000000-0000-0000-0000-0000-0000-000001"
becomes
                lvol1 {
                        id = "000000-0000-0000-0000-0000-0000-000002"
etc.

Then:
  vgcfgrestore oradata1_a
