Chapter 3 Loading AXD Tools 15
When you change the startup disk in System Preferences, 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 “Changing
the Startup Disk Temporarily at Startup” on page 16.
To change the startup disk in System Preferences:
1 Open System Preferences on the Xserve, and then select Startup Disk.
2 If the lock icon is locked, click it, and then authenticate as a system administrator.
3 Select the startup disk with the AXD tools and click Restart.
After you’re done using AXD tools, change the startup disk back to the volume you
were previously using.
Changing the Startup Disk Using the Command-Line
Interface
If your Xserve can load Mac OS X Server, you can use the command-line interface to
change its startup disk. You can use the command-line 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
“Changing the Startup Disk Temporarily at Startup” on page 16.
You’ll need to be able authenticate as the root account to change the startup disk in
the command-line interface.
Note: The Terminal commands described in this task are case-sensitive and must be
entered as described.
To change the startup disk using the command-line interface:
1 Open Terminal (located in /Applications/Utilities).
2 If you want to connect to a remote server, enter the following in the Terminal window,
and authenticate when requested:
ssh username@serveraddress
Replace username with the short name of a user who can authenticate as the root
account on the server. Replace serveraddress with the URL, IP address, or host name of
the server.
