Block Devices are only supported on Linux. On other Unix platforms, the directio symantics are not applicable (or rather not implemented) for block devices. Note: The support for raw/block devices is scheduled for Oracle Database 12g. The Oracle Database 10g OUI does not support block devices however Oracle Clusterware and ASM do. With Oracle RAC 11g Release 2, the Oracle Universal Installer and the Configuration Assistants do not support raw or block devices anymore. The Command Line Interfaces still support raw/block devices and hence the Oracle Clusterware files can be moved after the initial installation.
