Hi, > Well may be because since RAC works quite well with RAW devices and ASM are > like raw devices.... :-o With the difference that you'll have hard time getting your data back when ASM instance doesn't start up anymore and especially if the blocks describing ASM allocation unit locations and semantics get corrupted. Not that it has happened to me on real systems, but still I usually recommend to keep online redologs outside ASM on raw devices if the client definitely wants to use ASM. Tanel.
