Explanation

There are three types of disk groups based on the ASM redundancy level. he redundancy levels are: * External redundancy ASM does not provide mirroring redundancy and relies on the storage system to provide RAID functionality. Any write error cause a forced dismount of the disk group. All disks must be located to successfully mount the disk group. * Normal redundancy ASM provides two-way mirroring. By default all files are mirrored so that there are two copies of every data extent. A loss of one ASM disk is tolerated. * High redundancy ASM provides triple mirroring by default. A loss of two ASM disks in different failure groups is
