#vgchange -a y /dev/vgX
#vgsync /dev/vgX

But you have to do mkboot command since this disk is use to be bootable, see my precedent attached file...

No!
Follow these steps:
1. lvlnboot -A autobackup vg00
2. vgcfgrestore -n /dev/vg00 /dev/rdsk/cXtXdX
3. vgchange -a y /dev/vg00
4. mkboot /dev/rdsk/cXtXdX
5. mkboot /dev/dsk/cXtXdX
6. mkboot -a "hpux -lq" /dev/rdsk/cXtXdX
7. lvlnboot -R
8. lvlnboot -v (check again)
9. vgsync /dev/vg00
10. shutdown -r

Goodluck to you
