Hi
you shouldn't change the softRAID partition id to lvm
you had to create the lvm over the RAID

you can not create LVM/SW-RAID
you can make LVM over SW-RAID or SW-RAID over LVM

that is OK
but /dev/hda[1-3] and /dev/hdb[1-3] should be SW-RAID ( partition id)
and then
pvcreate /dev/md0 /dev/md1 /dev/md2
vgcreate
.........
good luck
