You can use a pre script to detect if is previously partitioned or not
and then use something similar to:
%pre
#!/bin/sh
Discover condition
if condition;
then
echo "part /boot --fstype ext3 --size=100 --ondisk=$DISCO" >>
/tmp/part-include
echo "part pv.100000 --size=1 --grow --ondisk=$DISCO" >>
/tmp/part-include
echo "volgroup Merca --pesize=32768 pv.100000" >> /tmp/part-include
echo "logvol swap --fstype swap --name=Swap --vgname=Merca
--size=2047" >> /tmp/part-include
echo "logvol / --fstype ext4 --name=root --vgname=Merca
--size=2048" >> /tmp/part-include
echo "logvol /home --fstype ext4 --size=1000 --name=home
--vgname=Merca" >> /tmp/part-include
else
echo "part /boot --fstype ext3 --size=100 --ondisk=$DISCO" >>
/tmp/part-include
echo "volgroup Merca --pesize=32768 --useexisting --noformat" >>
/tmp/part-include
echo "logvol swap --fstype swap --name=Swap --vgname=Merca
--size=2047 --useexisting --noformat" >> /tmp/part-include
echo "logvol / --fstype ext4 --name=root --vgname=Merca
--size=2048 --useexisting --noformat" >> /tmp/part-include
echo "logvol /home --fstype ext4 --size=1000 --name=home
--vgname=Merca --useexisting --noformat" >> /tmp/part-include
fi
Later in the partitioning section use %include /tmp/part-include
Hope this helps to you :)

Hi there,
Is there a possibility in the kickstart syntax to partition/format a
device, but only if it's not already partitioned/formatted.
Use case: I have a server with a data disk. First time deployment it
should be partitioned and formatted. Second time, the data partition
must be left as is and only mounted.
I now about --noformat, but how to make that conditional?
If not possible, I must use %post. Any examples on how to do this
there using bash or python?
Regards,
Fred
