AIX Essentials
One of the most primary of support roles is the installation of a new software image or updating an existing one. In this chapter, the most common ways of performing these tasks are discussed.
There are three types of installation methods:
Use this method if you have a new machine or if you want to completely overwrite an existing version of the Base Operating System (BOS) that is installed on your system. The New and Complete Overwrite installation overwrites all data on the selected destination disk.
Use this installation method to upgrade AIX between versions and releases, while preserving the existing root volume group. This method preserves all file systems except /tmp, as well as the root volume group, logical volumes and system configuration files.
Use this installation method when a version of BOS is installed on your system and you want to preserve the user data in the root volume group. However, this method overwrites the /usr, /tmp, /var, and / (root) file systems by default, so any user data in these directories is lost. These file systems are removed and recreated, so any other LPPs or filesets that you installed on the system will also be lost.
To upgrade AIX modification levels, use the SMIT fastpath smit update_all.
The following sections describe the installation methods in more detail.
