This doesn't look promising (although I've not had to recover a system like
this so I may be pessimistic). Your hdisk1-3 are not in a volume group
(which is not surprising because you've replaced your boot disk. If they
were all part of the original rootvg volume group I suspect that the data on
them is effectively lost too.
If they were on another volume group or groups you may be able to recover
them with the importvg command, but you would need to kno the original
volume group names.
If the data on these disks isn't important because you have it all backed
up, simply use SMIT to add these disks to rootvg or create other volume
groups and add these disks to them. You can then create the desired logical
volumes and from there create the filesystems. (ie a volume group contains
one or more physical disks, each volume group is divided into one or more
logical volumes, and each logical volume will contain one file system, which
is the thing that you actually mount.)
Without a layout of the original volumes you may have trouble getting this
right. Do you have the output of lsvg, lsvg rootvg, lsvg -l rootvg, df, or
mount? That may be a start...
