Using IBM Installation Toolkit Network installation PowerLinux

In many scenarios, using a network to install PowerLinux is a good, even necessary choice, for example, to install a very multiple partition powerlinux, or to install a partition that does not have a physical optical drive or a virtual CD drive to install.

Two kinds of powerlinux, whether Red Hat or SUSE, have their own network installation methods, but one is the configuration process is more complex, the other is the two kinds of Linux to do network installation of different methods, to the PowerLinux administrator caused management difficulties.

IBM installation Toolkit for PowerLinux is a tool CD developed by IBM to facilitate installation, migration, and configuration of PowerLinux. It provides a very easy to deploy PowerLinux network installation solution, and can provide a different powerlinux distribution on one installation server source, in addition, it also provides a good graphical configuration interface, this is just contact PowerLinux users favorite.

The IBM installation Toolkit for PowerLinux CD is not included in the Power Server installation CD, you can download the ISO file directly from the IBM website and download the address at the second section of the Reference Resources section.

The following is an example of Red Hat 6.2 and IBM installation Toolkit 5.2.1, which describes the process of implementing a network installation in detail.

Get ready:

CD or ISO files for Red Hat 6.2 and IBM installation Toolkit 5.2.1;

Two partitions, one of which can be installed as a network installation server through a physical or virtual optical drive, and a network-installed client that can access the installation server.

Preparing the PowerLinux network installation Server environment

With the IBM installation Toolkit and Red Hat 6.2 installation discs, you can quickly install an installation server that already contains IBM PowerLinux-related packages. For installation steps, refer to the first article in the "Reference resources" section of the article.

The POWERLINUX environment installed with IBM installation Toolkit automatically includes software packages for IBM PowerLinux, such as support for PowerVM dynamic logical Partitions (DLPAR), implemented without restarting P On the premise of Owerlinux partition, the resources of processor, memory and I/O board are adjusted online, tool software supporting the graphical interface to configure different types of service, and the tool software of supporting network installation described in this article, etc. In addition, you can choose to install different versions of IBM Java during the installation process.

After the installation is complete, create a local YUM source for Red Hat to facilitate the installation of the desired package.

First mount the Red Hat installation CD to the local directory.

# mount/dev/cdrom/mnt

Depending on your actual environment, modify and execute the following script to quickly create a local YUM source.
