Yes.

The easiest way is :

1. mkszfile
2. Edit /image.data and add in multiple copies -
in the lv_data section change COPIES = 2 for each lv (might be some
other fields to change - compare a mirrored to a non-mirrored lv to
check).
3. Take the mksysb but DO NOT use the -i option (since this will
create a new image.data file which overwrites your old one).
4. Restore the mksysb.

If you are installing from CD, then the answer is no.

Why would you want to do this ? Can't you wait until the system is
installed and then mirrorvg ?

If you want to get all funky, you should check out the
alt_disk_install command to see if that can accomplish what you
desire.
