If you run lvlnboot and try to set the boot volume but it gives you the error saying that the boot volume should be the first logical volume

root@hpux:~ # /usr/sbin/lvlnboot -b /dev/vg00/lvol1
lvlnboot: Boot volume should be the first logical volume on the physical volume

Check with pvdisplay and check which volume shows on the Physical Extents section. It must match with the logical volume you’re declaring above.

In this case, it should show /dev/vg00/lvol1 instead of /dev/vg00/lvermhome

root@hpux:~ # pvdisplay -v /dev/disk/disk31_p2 | more

I mirrored a new disk to replace the old boot disk. So that’s why it showed this message in this case.
