Mirror/UX

Hi everybody!
I have L-1000 under HP-11.0 with two hard disks(c1t2d0-system, c2t2d0-unused). I need to make mirror of the system disk to the second one. After installing Mirror/UX product I did the following steps:
ISL>hpux ???lm
# vgchange ???a y vg00
# pvcreate ???B /dev/rdsk/c2t2d0
# vgextend /dev/vg00 /dev/dsk/c2t2d0
#mkboot /dev/rdsk/c2t2d0
After that system reported: Could not open /user/lib/uxbootlf: No such file or directory
So I needed to run to the first level
# init 1
#mkboot /dev/rdsk/c2t2d0
#mkboot ???a ???hpux ???lq??? /dev/rdsk/c2t2d0
#lvextend ???m 1 /dev/vg00/lvol1 /dev/dsk/c2t2d0
#lvextend ???m 1 /dev/vg00/lvol2 /dev/dsk/c2t2d0
#lvextend ???m 1 /dev/vg00/lvol3 /dev/dsk/c2t2d0
??????????????????????????????????????????????????????..
#lvextend ???m 1 /dev/vg00/lvol10 /dev/dsk/c2t2d0
#lvlnboot ???R /dev/vg00
#lvdisplay ???v /dev/vg00/lvolN was OK
But when I tried to boot from the c2t2d0 by switching off the c1t2d0 and assigning the path of the first as ALT and the second one as PRI and attempted to load
ISL> hpux ???lm for vgchange ???a y ???q n vg00
system began to panic. My question-what is my fault?

Dear ,
lvlnboot -b /dev/vg00/lvol1
lvlnboot -r /dev/vg00/lvol3
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2
lvlnboot -R ( this??? R ??? option will automatically do the ??? ???r , -s , -b , -d options. )if it is not doing then do it manually.
Execute this Command for Verification
#lvlnboot -v
It need look like this:
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c1t1d0 -- Boot Disk
/dev/dsk/c1t2d0 -- Boot Disk
Boot: lvol1 on: /dev/dsk/c1t1d0
/dev/dsk/c1t2d0
Root: lvol3 on: /dev/dsk/c1t1d0
/dev/dsk/c1t2d0
Swap: lvol2 on: /dev/dsk/c1t1d0
/dev/dsk/c1t2d0
Dump: lvol2 on: /dev/dsk/c1t1d0
/dev/dsk/c1t2d0

Hi,

After creating mirror you should do:

lvlnboot -b /dev/vg00/lvol1
lvlnboot -r /dev/vg00/lvol3
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2

If you have diagnostics installed, you shoud also update LIF area on mirror disk (in order to let diagnostocs function correctly from mirror boot disk):

mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p -p... /dev/rdsk/...

Later,
