Installing HP-UX 11.0 and Updating HP-UX 10.x to 11.0 HP 9000 Computers Edition 1

Appendix A 211
Configuring for a DHCP Server
Setting Up a DHCP Server
Callback
Routines: None is necessary.
g. Once the parameters are all filled in, then press OK on the Add
DHCP Group screen. SAM will then make the modifications to the
/etc/dhcptab file.
h. You will now want to use the Action menu to Enable boot Server (if
it is not already enabled).
5. Now, new systems that are installed with HP-UX 10.20 (or newer) or
booted with a pre-installed 10.20 (or newer) version of HP-UX should
contact this server to get an IP address lease and other network
information provided by the server.
Details of the DHCP
Services
• When doing a cold install of the HP-UX Operating system (version
10.20 or newer):
The installation tools will broadcast out on the network for any
available DHCP servers. The first server to respond will be chosen to
provide the default network information that the user is presented
with.
In the network parameters screen during a Cold Install, you see the
question: "Is this networking information only temporary?". The
"yes" or "no" answer to this implies the following:
•"no": Answering "no" (the default) means that if the IP address
and hostname were leased from an DHCP server, then that lease
will be retained after the install is done, so that the first boot of
the system will attempt to renew the same lease.
•"yes": Answering "yes" implies that the IP address and hostname
lease should be returned to the server after the installation is
complete. In this case, the first system boot will try to get a new
lease. This is most useful when the system is being installed on a
network that is different from its final destination.
(This answer to the question can also be set in the configuration
file with instl_adm(1M) using the keyword
is_netwk_info_temporary).
When automating system installations, the DHCP services allows
systems to get networking information without the need to make a
mapping in the Ignite-UX configuration files. (See instl_adm(1m) and
instl_adm(4)).
