HP-UX 11i v3 Installation and Update Guide, September 2009 (Update 5 Release)

Backing up your configuration files
If you plan to cold-install HP-UX 11i v3 on a system that already has HP-UX installed,
and you want to have that system serve the same role as it did before, then you will
want to preserve your configuration files. Such files include the following:
• Configuration files in /etc
• The contents of /usr/local
• Any local home directories (that is, those you do not import from another system)
• Any configuration files located in the /etc/opt directories for installed software
Collecting information about your system
Before you cold-install HP-UX 11i v3, you should collect information about your existing
system. Then, when you are installing HP-UX 11i v3, you will have the information
available when needed. This section contains tables where you can record the
information.
Use the collection tables in the following situations:
• When you choose the Advanced Installation (the default Ignite-UX option starting
with version C.7.5), an interface gives you the opportunity to enter all of this data
at the beginning of the install. The interface is a tabbed file folder and is
character-based.
• If you choose to network-enable your system, you must designate a unique host
name, host Internet Protocol (IP) address, and other network information for your
server.
Contact your site network administrator for the details to include in these tables.
NOTE:
During an installation, Ignite-UX configures the root, dump, and swap devices with
the new HP-UX 11i v3 mass storage stack agile addressing representation. This means
that, after installing, the commands that display the boot, dump, and swap devices
will show them using the agile form. During a cold-install of HP-UX 11i v3, both legacy
and persistent DSFs are automatically created. By default, the installation process will
configure system devices like the boot, root, swap, and dump devices to use persistent
DSFs. For more information on the new mass storage stack, see the white paper “The
Next Generation Mass Storage Stack: HP-UX 11i v3” (http://www.docs.hp.com/en/
oshpux11iv3.html#Storage%20Area%20Management).
Miscellaneous data collection table
Table 5-1 may contain some items that are not familiar to you, but you will be prompted
for this information during the install. However, the install process describes all options
in detail, so you can defer making decisions about items that are unfamiliar to you
until you reach that point in the install.
