Solution1. Create a physical volume with a boot reserved area
"pvcreate -B /dev/rdsk/c1t6d0"
2. Add the physical volume to the root VG
"vgextend /dev/vg00 /dev/dsk/c1t6d0"
3. Use mkboot to place the boot utilities in the boot area and add the AUTO file
"mkboot /dev/rdsk/c1t6d0"
"mkboot -a "hpux -lq" /dev/rdsk/c1t6d0"
4. Use mkboot to update the AUTO file on the primary boot disk
"mkboot -a "hpux -lq" /dev/rdsk/c0t6d0"
5. Use lvlnboot to identify the root, boot, primary swap and dump lvols
"lvlnboot -r /dev/vg00/lvol3 /dev/vg00" (lvol4 if you have secondary swap in lv
ol3)
"lvlnboot -b /dev/vg00/lvol1"
"lvlnboot -s /dev/vg00/lvol2 /dev/vg00"
"lvlnboot -d /dev/vg00/lvol2 /dev/vg00"
"lvlnboot -v"
6. Mirror the stand, root and swap logical volumes in order
"lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t6d0"
"lvextend -m 1 /dev/vg00/lvol2 /dev/dsk/c1t6d0"
"lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c1t6d0"
7. Then mirror the rest of your root logical volumes
"lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c1t6d0"
etc.
8. Modify your alternate boot path
"setboot -a 8/8.6.0 # use the path of your new boot disk"
9. Edit /stand/bootconf and add your new mirrored boot disk.
That's all there is to it.
For Itanium architecture, follow this guide:

And, for 11.31, follow this:

Re: how to mirror vg00
Setting up vg00 LVM mirroring differs on PA-RISC and on Itanium servers slightly. See appendix-D here:

Re: how to mirror vg00
> reboot is required or not
No reboot is required to allocate or to deallocate LVM mirroring.
