Migrating an Existing Volume to a RAID Volume
When you purchase a computer with the RAID card installed but no solid-state drive,
the startup disk is already congured as a single-drive Enhanced JBOD RAID set. You
can convert this RAID set, along with one, two, or three other drives, to a RAID volume
using the Migrate RAID Set command. All les on the original disk are retained in the
new RAID volume. Any data on the additional drives is erased.
To migrate to a RAID volume:
1 Start up your 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 at the top of the screen.
3 Choose Utilities > RAID Utility.
4 Select the existing RAID set, which supports your current startup volume, in the left
column of the RAID Utility window.
5 Click Migrate RAID Set in the toolbar or choose RAID > Migrate RAID Set.
6 Choose the type of RAID volume you want to create.
Maximum Protection: Migrates your system to a RAID volume based on either the RAID
1 or RAID 5 level, depending on the number of drives available.
Maximum Performance: Creates a volume based on the RAID 0 level.
To see the type of RAID set that will be created, look below the drive icons.
7 Choose the additional drives you want to include in the volume.
