Changing the Startup Disk Using the Command-Line Interface
If Mac OS X Server starts up by default on your Xserve, you can use the command-line
interface to change its startup disk. You can use the command-line interface to start up
from internal volumes and connected portable storage device volumes.
You can also change the startup disk of a remote server using the command-line
interface. Remote login must be enabled on the remote server (enabled by default).
You can enable remote login in the Sharing pane of System Preferences.
When you change the startup disk using the command-line interface, you can’t select a
startup disk with AXD EFI tools installed. To change the startup disk to the volume with
AXD EFI tools installed, change the startup disk at startup. For more information, see
