mrconfig dg create raid0

Creates a disk group striped for RAID 0.

CAUTION
The mrconfig command must be run under the supervision of HPE support.

The mrconfig dg create raid0 command creates a disk group striped for RAID 0. When you create a disk group, Data Fabric assigns one of the disks as the device path of the disk group. After you create a disk group, you are ready to create a storage pool on the disk group.

See mrconfig for instructions about running mrconfig commands.
