Your problem is probably in your partitioning schemes. Try
building
with each scheme via kickstart. If they work then the
problem is
probably in your logic, where I already see one issue. set
two drives
to -eq, not -ge as 3 is always greater than 2.

I've tried that example already, as well, but the partitions
never get
created, with the more advanced code below:
set $(list-harddrives)
let numd=$#/2 # This will provide the total # of drives
d1=$1 # This is the device of disk 1
d2=$3 # This is the device of disk 2, etc.
d3=$5
d4=$7
d5=$9
S1=$2 # This is the size of disk 1
S2=$4 # This is the size of disk 2, etc.
S3=$6
S4=$8
S5=$10
# This would be a partition scheme for three or more drives
if [ $numd
-ge 3 ] ; then cat << EOF >> /tmp/partinfo
