I could not quite understand what you want to do but ut sounds like you want to mirror an 18GB disk to a second 36GB disk. If this is correct please see this very recent thread for the drawbacks:

Hi Eduardo,

Good day to you !
If you would like to configure a mirror on your 2 x 18 GB boot disk (vg00) you need :

1. have mirror/UX software

run the command below :
# swlist -l fileset | grep -i mir

which should return the LVM-MIRROR- RUN fileset:

LVM.LVM-MIRROR-RUN B.11.11 LVM-MIRROR-
RUN

if you dont have, you need to purchase it.

2. have 2 x 18 GB harddisk also

since you have 'max PE per PV : 4350', unless you change the 'max PE per PV' parameter.

To change the parameter, you need to reinstall the OS OR use ignite/UX features. Backup your system with make_tape_recovery, restore it with some changes on 'max PE per PV'.

Other than that, you can check the detail steps on mirroring the boot disk on the document at this url below (docid : LVMKBRC00005103) :

Hope this information can help you.
