Description
The mksnetboot command configures network boot clients and the boot images
required to boot them. Both NIM Resource and Classic methods are handled. See
Chapter 13, “Network Boot/Installation Configuration”, on page 13-1 for an
explanation of NIM Resource and Classic netboot methods.
A boot image is created when a new client is configured. Boot images might need
to be updated if any server software is updated. For example, if the NIM spot has
a new software level applied to it, the corresponding boot images built from that
spot should be updated.
For the Classic netboot method, the boot images should be updated if any software
is applied to the netboot server (its /usr filesystem). The default case is to update
all known boot images if an update is requested.
Configuring a Network Boot Client Machine
Classic Method: Specifying the -h, -a and -d arguments generates the information
needed to respond to the client’s BOOTP request and assigns the client the specific
boot image used to boot the client, depending on the client’s machine type.
However, if you do not specify the -a option, the command requires, at a
minimum, the -S, and optionally the -s, and -g flags to add a client using this
method.
You only need to run this command for clients who will boot from the server. For
clients that will boot from other media, such as installation diskettes or tape but
will only install from this server, you do not need to run this command.
If the network adapter has been changed in the client system, you might need to
update the server to reflect the new hardware address of the client machine. You
can update the boot client information if already configured by following the same
steps as for a new client. This overwrites the previous information.
