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.
