SolutionThe -B option is used to create a bootable Physical Volume.
2) Mkboot /dev/rdsk/c3t6d0
Make sure to use the character device file when using mkboot.
3) Mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c3t6d0
4) Vgextend /dev/vg00 /dev/dsk/c3t6d0
This adds the Physical Volume to the root volume group
5)
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c3t6d0
This command extends the mirror to the specified Physical Volume.
*NOTE: The lvextend command has to be done on all logical volumes on the primary disk.
This means that lvextend has to be done on lvol1 -> lvolX. This also includes
/dev/vg00/lvol2, which by default is primary swap. Lvol1 must be the first logical volume Mirrored; if it is not, then you will not be able to boot from the mirror.
6) lvlnboot -r /dev/vg00/lvol3 Specifies the root logical volume.
7) Lvlnboot -s /dev/vg00/lvol2 Specifies the swap logical volume To determine where the swap logical volume is located Use the swapinfo command.
8) Lvlnboot -d /dev/vg00/lvol2
Specifies the dump logical volume
9) lvlnboot -b /dev/vg00/lvol1
Specifies the boot logical volume
10) lvlnboot -R
Recovers any BDRA info
11) lvlnboot -v
Verify boot, root, swap and dump settings.
12) setboot
This will display the Primary and Alternate boot paths that are currently set.
13) setboot -a mirror_disk_hardware_address
Changes the Alternate Boot Path to the path of the Root Mirror.
14) shutdown -r now
Shut down the system and boot from the mirror disk.

Re: Mirror
should we always do the mirror like this ?
why ?
- lvextend -m 1 lvol1 (boot)
- lvextend -m 1 lvol3 (root)
- lvextend -m 1 lvol2 (swap > 2GB)
why should we change the order lvol1, lvol3, lvol2
thanks
