NIM Method: When you add a network boot client that uses NIM resources, the
-d, -T, -k, -S, -s, -g, and -a flags are not valid. The information that would be
contained in these flags is contained in the NIM resource definition for the client.
The required flags to add a NIM Resource Network Boot client are -h, -n, and -l.
Rebuilding Existing Network Boot Images
If you update or install software on the boot source, you must also update the boot
image. For the Classic boot method, the boot source is the /usr directory of the
boot server. For the NIM Resource Network Boot, the boot source is the NIM
SPOT resource.
To rebuild the boot image for either method, use one of the following commands.
To rebuild all existing boot images, type:
mksbnetboot -B ALL
To rebuild a specific build image, type:
mksbnetboot -B <image name>
A Note about the Network Hardware Address
The -a flag is used to specify the adapter “hardware” address, which differs for
each adapter manufactured. The adapter address is needed by the server before it
can respond to BOOTP requests. If you do not know the client network adapter
hardware address, follow the instructions in “Determining the Network Adapter
Hardware Address” on page B-5.
Enter this parameter only for PCI-based RISC System (rspc) clients, or if you want
the client to boot using a broadcast BOOTP request. By entering the adapter
hardware address for a non-rspc client, that client can be booted without filling out
the server information in the BOOTP screen at system startup. This is
accomplished by sending a broadcast BOOTP request that the server responds to
by identifying the hardware address of the client’s network adapter. This
information is not used by non-RISC PC clients requiring a gateway to reach the
server.
Flags
-a “address”
Specifies the adapter hardware address of your network adapter. Note that this
is not referring to the Internet (IP) address, but the hardware adapter address.
This information is required on PCI-based RISC System (rspc) clients and is
not used by other clients requiring a gateway to reach the server.
-d “net device”
Specifies the name of the network adapter for the network the clients will be
booted from. You can also specify a network adapter type of either ethernet or
token-ring if a device of the client’s network adapter type does not exist on the
server.
-g “gateway”
Gateway address the client must use to reach this server, if any.
-h “hostname”
Specifies the name of the host to which the boot image is to be assigned or the
client to be removed from the network boot configuration.
-k “kernel”
Indicates the kernel type, either “up” for uniprocessors or “mp” for
multiprocessors.
