MapR 5.0 Documentation : mrconfig dg create concat


The mrconfig dg create concat command creates a concatenated disk group. When a disk group is created MapR assigns one of the disks as the device path of the disk group. After you create a disk group you will be ready to create a storage pool on the disk group.
