How to upgrdae Oracle Cluster on Red Hat Linux 3 to Red hat Linux 4 AS U 7

Question

We need to upgrade our Clustered (2 Nodes) Oracle Database environment on Linux environment to Red Hat 4 AS 7. The current OS version is Red Hat 3 update 6. We use EMC SAN Storage as shared storage (OCFS and Raw Devices) for our 9i and 10g databases
Question: We will install (on local disks) Red Hat 4 AS Update 7 and then install ocfs and ASMlib RPMs. Is there any risk of loosing the existing (on Red Hat 3 update 6) ocfs file systems and raw devices (from EMC SAN Storgae) after we do fresh install of OS and ocfs and ASMlib RPMs? How can we keep the shared storage data quickly available (without restore from the backup) to the system after installing Red Hat 4 AS Update 7 and mentioned RPMs?
