You can nd instructions for partitioning the hard disk into multiple volumes, creating
a RAID set, and erasing the target disk or partition by viewing Disk Utility Help. To view
Disk Utility Help, open Disk Utility on another Mac computer with Mac OS X v10.6 and
choose Help > Disk Utility Help.
From the command line
You can use the diskutil command-line tool to create a RAID set. Normally, you would
use a remote shell (SSH) to log in to the newly started computer to use this method.
You can use diskutil to can create a RAID volume that is Mac OS Extended format,
Mac OS Extended (Journaled) format, Mac OS Extended format (Case-Sensitive) format,
Mac OS Extended (Journaled, Case-Sensitive) format, or MS-DOS FAT format. However
keep in mind the following:
You cannot create a RAID from the startup disk. Â
When creating RAID sets or adding disks, specify the entire disk instead of a Â
partition on that disk.
All potentially destructive diskutil operations must be done with superuser or root Â
privileges.
For complete command syntax for diskutil, consult the tool’s man page.
Use command-line arguments that apply to your specic needs. The following
command is a sample, which creates a single mirrored RAID set (RAID 1) from the rst
two disks installed in the computer (disk0 and disk1), with the resulting RAID volume
called MirrorData.
The basic syntax is:
diskutil createRAID mirror setName format device device ...
So the command is:
diskutil createRAID mirror MirrorData JournaledHFS+ disk0 disk1
