The mirror group removal operation also removes disk partitions on disks except the read disk in the mirror group allowing only the read disk to maintain disk partitions and data. To keep disk partitions and data on a disk other than the read disk, remove the other disks from the mirror group and reboot the system before removing the mirror group.
