Chapter 3 Setting Up NetBoot Service 53
6 Click Save.
From the Command Line
You can also specify a volume to store shadow files on by using the serveradmin
command in Terminal. For more information, see the system image chapter of
Command-Line Administration.
Using Images Stored on Remote Servers
You can store NetBoot or NetInstall images on separate remote servers other than the
NetBoot server. You must copy the images from the NetBoot server to the remote
server and then configure the remote server to use the images.
To store an image on a separate remote server:
1 Copy the image.nbi folder from the NetBoot server to the remote server on a NetBoot
sharepoint (/Library/NetBoot/NetBootSPn).
If the image is on the remote server, you can create the .nbi folder on the NetBoot
server by duplicating an existing .nbi folder and adjusting the values in its
NBImageInfo.plist file.
2 Open Server Admin and connect to the remote server.
3 Click the triangle to the left of the server.
The list of services appears.
4 From the expanded Servers list, select NetBoot.
5 Click Settings, then click Images.
6 For each image you want your clients to see from the remote server, click the checkbox
in the Enable column.
7 Select the protocol you want NetBoot to use when serving your image (NFS or HTTP).
8 Click Save.
Specifying the Default Image
The default image is the image used when you start a client computer while holding
down the N key, providing that the client hasn’t selected a NetBoot or NetInstall
volume via Startup Disk. See “Starting Up Using the N Key” on page 58.
If you’ve created more than one startup disk image, you can use the NetBoot service
settings in Server Admin to select the default startup image.
Important: If you have diskless clients, set their boot image as the default image.
If you have more than one NetBoot server on the network, a client uses the default
image from the first server that responds. There is no way to control which default
image is used when more than one is available.
