Take a look at my answer in this previous post, it may help. It has to do with the order your LVs are mirrored.

Hi:

What release? If this is 11.0 and you are using disks connected to an A5838A
SCSI card for swap or dump space, then this won't work according to Technical Knowledge Base document #KBRC00010650.

If this is not the case, please post more specifics -- OS level, the patch you are referencing, and the hardware in question.

Regards!

SK.
Can you show me how to display the current information of swap.?
I am not doing mirroring of device,
what i did is to configure a new vgboot and use cpio to copy over the information?...

Hi (again):

The thread SK posted details some of the issues. One question is the order and the extent of the first three logical volumes -- they should/must occur in the order: lvol1, lvol2, lvol3, where 1=/stand, 2=swap/dump 3=/.

Post, please, the output of the following:

# for N in 1 2 3
> do
> lvdisplay -v /dev/vgXX/lvol${N}
> done

...where vgXX is the volume for which you are attempting to do the 'lvlnboot'. Again, the hardware specifics, OS-level, etc. are always important.

Regards!

Sounds like you're manually duplication a boot disk. Am I right ? Can you outline what are the steps/commands you used ? In particular when you create your LVs on vgboot did you ..(I'm using c2t2d0, lvol1-84MB-/stand, lvol2-2048MB-pri swap and lvol3-200MB-/ in my example)..
/stand
====
# lvcreate -C y -r n -n lvol1 /dev/vgboot
# lvextend -L 84 /dev/vgboot/lvol1 /dev/dsk/c2t2d0
swap
====
# lvcreate -C y -r n -L 2048 -n lvol2 /dev/vgboot
/
==
# lvcreate -C y -r n -n lvol3 /dev/vgboot
# lvextend -L 200 /dev/vgboot/lvol3 /dev/dsk/c2t2d0
.. run the above in that order ?

hi SK.Chan,
I have used the procedure as you posted to manually replicate the rootvg using cpio, however, i have ran into this error when trying to do
swap logical volume size beyond the IODC max address
the os is on 11.0 and rev 41.2 ?
don't know whethere or not the PDC firmware level need to be updated in order for the host to boot via fiber??
