Digital UNIX Version 4.0 supports full, custom, and cloned installations for new systems and an update installation that allows users who already have Version 3.2C, 3.2D-1, or 3.2D-2 of the operating system installed to update to Digital UNIX Version 4.0 without overwriting system files. Also, Digital UNIX Version 4.0 supports a variety of setup utilities that allow users to configure their systems quickly and with relative ease.
Both the installation and setup utilities use a graphical user interface (GUI) on systems that support graphics and a text-based interface on systems that do not.
Additionally, the CD-ROM used to install Digital UNIX Version 4.0 contains file systems
that are laid out just as the software would be installed on the
system. It has directly accessible
root,
/usr,
and
/var
areas. This format makes almost every operating system command and
utility available to the installation process because your system
actually mounts the installation media and runs off of it during the
installation. You therefore have access to a complete, albeit
generic, Digital UNIX operating system during the installation
itself. This means that the UNIX commands required for recovery
procedures, such as restoring corrupt file systems, are readily
available even if your operating system is not yet fully functional.
Also, if you inadvertently delete a system file, you have easy access
to the file on the CD-ROM. The RIS area from which you invoke an
installation is laid out in the same format as the CD-ROM and provides
the same advantages.
Digital UNIX Version 4.0 supports full, cloned, and update installations either from a CD-ROM or across the network from a Remote Installation Services (RIS) server. For more information on RIS, see the guide Sharing Software on a Local Area Network.
Note
The RIS software is available in the Server Extensions kit and requires a separate license and PAK to access. For more information, see Chapter 1 and the Software Product Description for Digital UNIX Version 4.0.
A full installation allows users to install Digital UNIX Version 4.0 on new systems and is divided into the following three procedures:
A default installation installs all mandatory software subsets
onto a single disk chosen by the user. Additional
optional subsets can be installed later (if there is room on the
disk) by using the
setld
command.
The default installation is intended for those users who do not want to customize their disk partitions, install across multiple disks, and who want to get the operating system up and running quickly and easily.
A custom installation
is thoroughly configurable,
allowing users to select disks and partitions for
the
root,
usr,
and
var
file systems
and for
primary
and secondary
swap.
In addition,
the custom installation
allows users to select from a list of optional software
subsets,
rather than
automatically installing only the mandatory subsets.
The Custom Installation is intended for users who install across different disks and who know which optional subsets they need to install.
A cloned installation lets you duplicate the file system layout, file system type, and software subset selections from a similar type system that has already been installed with Digital UNIX Version 4.0. A cloned installation can only be performed using RIS. If your system is registered to a RIS environment and a configuration description file (CDF) is specified, the installation procedure retrieves the CDF and uses the system configuration information stored in the CDF to configure and install your system.
For more information on full installations, see the Installation Guide.
The Update Installation allows users to update their systems to a new version of the operating system without overwriting customized system files, user files, altering file systems, or destroying existing disk partitions.
Note
Your system must be running Digital UNIX Version 3.2C, 3.2D-1, or 3.2D-2 in order to update install to Digital UNIX Version 4.0.
The
installupdate
utility invokes
the update installation
and
does the following:
/etc/passwd
and
/etc/fstab.
If something new is delivered in a system file that you have customized, or if a system file has changed, the update installation attempts to merge your file with the new file. Although the update installation attempts to merge files automatically, it writes a log of those files that must be merged manually.
Once the update installation is complete,
you can load additional subsets using the
setld
command.
For more information on the update installation, see the Installation Guide and the Update Installation Quick Reference Card.
Once the
Digital UNIX Version 4.0
software is installed, if you have graphics capabilities, you can
use the
SysMan
Configuration Checklist
to set up your system. The first time you log in as
root
after a system installation or the
first time you log in to a factory installed software (FIS) system,
the
SysMan
Configuration Checklist
displays the
SysMan
applications that are available to set up your system for general use.
Note
When you are logged in as superuser or
root, you can invoke the SysManConfiguration Checklistat any time by clicking on theConfiguration Checklisticon in theSystem_Administrationfolder, or entering the following command on the UNIX command line:
# /usr/sbin/checklist
The following utilities are available from the
SysMan
Configuration Checklist:
Many of the
SysMan
Configuration Checklist
utilities are also available in text-based interfaces that can be
displayed on systems that only have character-cell displays. See
Section 13.2.2
for more information.
