[root@ca-test1 /]# /etc/init.d/oracleasm configure

Configuration of CFS or Raw Devices

In the previous sections, we examined the creation and usage of the ASM instance resources. In this section, let us examine how to configure raw devices and Cluster File System. For studying the creation of raw partitions, we will follow a typical Linux environment and raw device configuration. For CFS, we will look into three products PolyServe Matrix Server, OCFS and Veritas CFS
