RE: Conversion of a 3 TB NON-RAC Database To "ASM" - RAC in 10gR2 ?

Thanks Nial for responding.  

If you mean continue to use a cooked / Mounted Cluster File system (CFS) in place of the RAW ASM devices for the RAC Database, e.g. Sun Shared QFS or the Veritas Storage Foundation for Oracle RAC (SFRAC) Mounted CFS?   (This would allow continuing with the traditional datafiles)  

Is Moving to & Managing the ASM Technology far more complex than the existing CFS Solutions like QFS, Veritas for RAC?

I had similar thoughts I suppose. You have a 3TB system that you want to be highly available. What then is the motivation for moving it from one storage technology to another, especially another more complex one. There are a number of filesystems that you can use for RAC databases and if you are in the market for the hardware/dr etc that is necessary to support a highly available 3TB system you likely won't have issues with paying for them.
