How to set Raid cache policies with DS?

We use DS solely for Server deployments. I am trying to configure the Read/Write cache policies using dynamic raid.
Does anybody know where to locate these settings in the dynamic raid job/script, and how to change the settings for Read ahead/Write through?
Particulars:
- Dell servers (2950, R710)
- Dell Perc 5i and 6i controllers
- Using DS 6.9 sp3
- Using Dell for DS 3.2
Thanks in advance for any suggestions.
