Chapter 5: Installation and Configuration ASM diskgroup creation The Oracle DBCA creates the ASM data diskgroup for the ASM instance. You can then create additional diskgroups. ASM uses mirroring for redundancy. ASM supports these three types of redundancy: • External redundancy. • Normal redundancy: 2-way mirrored. At least two failure groups are needed. • High redundancy: 3-way mirrored. At least three failure groups are needed. EMC recommends using external redundancy as protection is provided by the CLARiiON CX4-940. Refer to the CLARiiON configuration setup.
