To access the Classic Network Boot menus, select Classic Network Boot from the
Network Boot/Install Configuration menu.
Note: From a command line, type sb_netboot.
Configuring or Updating a Network Boot Image
The Network Boot Image exists on the Network Install Server, and is sent to the
client system only upon request in order to boot the client system to the SysBack
Installation and Maintenance Menus. This prevents the need to have boot media,
such as a tape or diskettes, available at the client in order to perform a network
install.
A separate boot image must be created for each type of network adapter to be
used for the network install. The available network install adapter types are
ethernet, token ring, and FDDI. A network boot image must be created for each
platform type as well. For example, an rspc platform can boot from the same
server as an rs6k platform, but each will use a different network boot image.
If you have applied AIX updates to your system, or have added software to
support new hardware on the client, then you should update the boot image using
this option. To update an existing boot image, follow the same instructions as
creating a boot image for the first time. The previous image file will be
overwritten, and any configured clients will begin using the new image
automatically.
Cloning systems: A System Backup created on one machine can be installed on
another machine with a different processor or machine type. If booting a client
machine of a different machine type or with a different hardware configuration,
you must have installed the device support on the server for all devices to be used
by the client machine. You must also have created a separate network boot image
for each platform type.
Adding or Changing a Network Boot Client
This option configures a network boot client that is to be booted from the server.
This option generates the information needed to respond to the client’s BOOTP
request, and assigns the specific boot image that will be used to boot the client,
depending on the client’s network adapter and platform type. If a network boot
image for this client’s platform, kernel, and device type does not already exist, a
boot image will be created in the /usr/lpp/sysback/netinst/bootimages directory.
Important Note: This option provides the client system with permission to mount
the server’s /usr filesystem in read-only mode. If you do not
want the client to be permitted read-only access to the server’s
/usr filesystem once the install has completed, use the Remove a
Network Boot Client option after installation.
If the network adapter changes on the client system, it is necessary to update the
server to reflect the new adapter type and hardware address of the client machine.
You can update the boot client information if already configured, using the steps
for a new client.
The adapter “hardware address” refers to the physical network adapter’s hardware
address, which differs from adapter to adapter. By entering an adapter hardware
