Setting Up RAID Volumes
There are two basic ways to set up RAID volumes:
Migrate your existing startup volume Â
Set up RAID sets and volumes manually Â
For examples of some typical setups, see “Setup Examples” on page 18.
Migrating your Existing Startup Volume
If you purchased your computer with a RAID card already installed and no solid-state
drive (SSD), a simple way to set up a RAID volume is to use the Migrate RAID Set
command to convert the existing startup volume, together with other empty disks in
the computer, to a new RAID volume in a single step. When you migrate your existing
startup volume, you don’t need to reinstall the operating system.
If your computer came with a solid-state drive, it’s set up as the startup drive and
there’s nothing to migrate. All of your disk modules are available for creating RAID sets
and volumes manually.
To migrate your disks to a RAID volume:
Follow the instructions under “ m Migrating an Existing Volume to a RAID Volume” on
page 7.
Setting Up RAID Sets and Volumes Manually
If you want more control over RAID set and volume setup, and you don’t mind
reinstalling Mac OS X or Mac OS X Server, you can use the Create RAID Set command
and the Create Volume command to set up your RAID storage.
To set up RAID sets and volumes manually:
1 Start up the computer using the Mac OS X or Mac OS X Server installation disc that
comes with the computer.
2 When the Installer opens, choose your language and click the Next button to see the
Utilities menu in the menu bar at the top of the screen.
3 Choose Utilities > RAID Utility.
4 In RAID Utility, use the Create RAID Set command and the Create Volume command to
create your RAID volumes.
For information, see “Creating a RAID Set” on page 8, and “Creating a Volume” on
page 9.
5 When you’ve created your volumes, quit RAID Utility.
6 Follow the Installer onscreen instructions to install Mac OS X or Mac OS X Server on
one of the new RAID volumes and restart the computer.
