Guidelines for Storage Options
Use the following guidelines when choosing storage options:
You can choose any combination of the supported storage options for each file type provided that you satisfy all requirements listed for the chosen storage options.
You can use Oracle ASM to store Oracle Clusterware files.
Direct use of raw or block devices is not supported. You can only use raw or block devices under Oracle ASM.
If you do not have a storage option that provides external file redundancy, then you must configure at least three voting files locations and at least two Oracle Cluster Registry locations to provide redundancy.
