Answer: BE Normal redundancy disk groups require at least two failure groups. High redundancy disk groups require at least three failure groups. Disk groups with external redundancy do not use failure groups. Oracle ASM instances mount disk groups to make Oracle ASM files available to database instances; Oracle ASM instances do not mount databases. https://docs.oracle.com/cd/E11882_01/server.112/e18951/asmcon.htm#OSTMG94053
