No Oracle RAC shares the same storage between two or more nodes.

What they had here would appear to be database A running on storage A which is replicated at the storage level to storage B where database B waits in an idle state. Because the replication system is "blind" - it only sees its own filesystem containing bytes, not Oracle data structures - it can't tell a good Oracle block from a bad one and copies it.

I do this sort of setup for a living and you would be amazed at how many "architects" there are around who have completely drunk the storage vendor kool-aid and don't really understand how anything works (not even storage...).

This is likely the case since the post mentioned that storage controller was initially blamed (but cleared).

I rarely work with Oracle, so I'm not very familiar with the product line. Thanks for the correction.
