RHEL4 or RHEL5 CD or DVD set (internal or external CD/DVD)
RHEL4 or RHEL5 ISO DVD image or KickStart image (network repository)

Note - KickStart is Red Hat’s automated installation method. It enables a system administrator to create a single image containing the settings for some or all installation and configuration parameters that are normally provided during a typical Red Hat Linux installation. Typically, a KickStart image is placed on a single network server and read by multiple systems for installation.

Note - If you received RHEL4 CDs from Sun, you might need to upgrade the RHEL4 operating system to Update 7 immediately after completing the installation.

Before You Begin

The following requirements must be met prior to performing the RHEL PXE installation:

If you are using a KickStart image to perform the installation, you must:

Create a KickStart file.
Create a boot media with the KickStart file or make the KickStart file available on the network.

Follow the KickStart installation instructions in the Red Hat Enterprise Linux 4: Administration Guide (http://www.redhat.com/docs).

To use PXE to boot the installation media over the network, you must:

Configure the network (NFS, FTP, HTTP) server to export the installation tree.
Configure the files on the TFTP server necessary for PXE booting.
Configure the Sun Fire X2270 Server MAC network port address to boot from the PXE configuration.
Configure Dynamic Host Configuration Protocol (DHCP).

Follow the PXE network installation instructions in the Red Hat Enterprise Linux 4: Administration Guide (http://www.redhat.com/docs).

Install RHEL4 or RHEL5 Using Network PXE Boot

1. Ensure that the PXE network environment is properly set up and the RHEL installation media is available for PXE boot.

2. Reset the power on the server.

For example:

From the ILOM web interface, select Remote Control --> Remote Power Control, then select the Power Cycle option from the Host action drop-down list box.
From the local server, press the Power button (approximately 1 second) on the front panel of the server to power off the server, then press the Power button again to power on the server.
From the ILOM CLI on the server SP, type: reset /SYS

The BIOS screen appears.

Note - The next events occur very quickly; therefore, focused attention is needed for the following steps. Watch carefully for these messages as they appear on the screen for a brief time.
