# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
disk 0 0/0/1/1.2.0 sdisk CLAIMED DEVICE HP 73.4GMAN3735MC
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0
disk 1 0/0/2/0.2.0 sdisk CLAIMED DEVICE HP 73.4GATLAS10K3_73_SCA
/dev/dsk/c2t2d0 /dev/rdsk/c2t2d0

Note: c1t2d0 is the boot disk and c2t2d0 is the mirrored disk.

1) Initialize the disk and make it bootable
pvcreate -B /dev/rdsk/c2t2d0
Note: the -B parameter tells pvcreate that this will be a bootable disk.

2) Add the physical volume to the volume group
vgextend /dev/vg00 /dev/dsk/c2t2d0

3) Use mkboot to place the boot utilities in the boot area and add the AUTO file.
mkboot /dev/dsk/c2t2d0
mkboot -a "hpux -lq" /dev/rdsk/c2t2d0

4) Use mkboot to update the AUTO file on the primary boot disk.
mkboot -a "hpux -lq" /dev/rdsk/c1t2d0

5) Mirror the stand, root and swap logical volumes
lvextend -m 1 /dev/vg00/lvol1
lvextend -m 1 /dev/vg00/lvol2
lvextend -m 1 /dev/vg00/lvol3

Note: LVM will resynchronize the new mirror copies.

Repeat the lvextend for all other logical volumes on the boot mirror.
lvextend -m 1 /dev/vg00/lvol4
lvextend -m 1 /dev/vg00/lvol5
lvextend -m 1 /dev/vg00/lvol6
lvextend -m 1 /dev/vg00/lvol7
lvextend -m 1 /dev/vg00/lvol8

#lvlnboot -v #recheck it


6) Modify your alternate boot path to point to the mirror copy of the boot disk.
Note: Use the Hardware path for your new boot disk.
setboot -a 0/0/2/0.2.0
