Updating and Installing: Why Do It?
Moreover, for a system being re-installed with Ignite-UX, the install
process can be initiated from the server with no local intervention at the
client system.
The System Administrator can also set up configuration files ahead of
time for existing systems. Ignite-UX will use these during install instead
of the default configuration. This can ensure that specific existing
systems get unique configurations.
Install Scenarios This manual presents a number of scenarios which will help you to follow
the following procedures:
• Updating your current OS and applications. This involves using the
SD-UX tools to install SD-packaged products and bundles onto your
existing system. It can serve to either update the OS or other
software, while leaving data files untouched. If you need to upgrade
from 9.0x, please see the manual Upgrading from HP-UX 9.x to 10.01.
• Installing a system from media. This is usually done with single or
few standalone systems, using a CD-ROM source.
• Installing a system from a network ("pull" from a client). This is done
with a small networked site (fewer than 50 clients and few servers),
and may or may not use a standard system image.
• Installing a number of systems from a network ("push" from a
server). This is done where there are many client systems and they
all generally require a similar installation. This may use a standard
system image, or "golden disk".
• Re-installing a number of systems from a network server. This is done
where the client systems are to be "updated" and their data is kept on
separate servers, so that only the OS and minimal system
information need to be re-installed. This may also use a standard
system image, or "golden disk".
• Building a recovery system for the target. This can be done while you
are in an install session.
Other "mixed scenarios" are also possible. For information on upgrading
a system from HP-UX 9.x, see the manual Upgrading from HP-UX 9.x to
10.x (HP Part No. B3782-90073).
The following Task-Information Roadmap will help you find information
on the main installation tasks you are likely to encounter.
