mrconfig dg create raid0

The mrconfig dg create raid0 command creates a disk group striped for RAID 0. When the 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.

See mrconfig for instructions about running mrconfig commands.
