Task 2: Start the Installation Process

Begin this procedure on the head node.

Turn off power on all nodes.

Turn on power to the head node.

Insert the DVD distribution media into the drive on the head node to boot from the DVD.

This step applies only to Itanium-based systems (HP Integrity servers). Skip this step for all other chip architectures and proceed to step 6.

After displaying some power-on messages, the node power-on process displays the Boot Menu. Use the arrow keys on the keyboard to select the DVD ROM as the boot device. How you do so depends on upon how the EFI environment is configured.

At the boot prompt, enter the appropriate boot command to start the installation process and specify the name of the Kickstart file (ks.cfg). You must act fast, because the system does not pause very long at the boot prompt. As listed in Table 3-7, the command line is different depending upon your cluster platform architecture and how your boot device was set.

	Note: Some hardware models require additional parameters to be included on the command line. Before booting the head node, look in the HP XC System Software Release Notes to make sure there are no additional command line options for your hardware model.

Table 3-7 Upgrade Boot Command Line Based on Cluster Platform Architecture

Cluster Platform	Architecture Type	Boot Command Line
CP3000 and CP4000	Opteron and Xeon	boot: linux ks=cdrom:/ks.cfg
CP6000	Itanium (when the boot device was set through the preconfigured boot option and the ELILO boot: prompt is displayed)	ELILO boot: linux ks=cdrom:/ks.cfg
CP6000	Itanium (when the boot device was set through the EFI Shell option and the fs0:> prompt is displayed)	fs0:> elilo linux ks=cdrom:/ks.cfg

When prompted, answer the questions listed in Table 3-6. You have the opportunity to confirm every answer before continuing to the next question.

When you have answered all questions, the unattended software load process begins. The total software load takes about 15 minutes. A progress bar is displayed as the Linux RPMs are loading.

As the XC specific RPMs are loading, the following message is displayed and remains on the screen for 5 minutes until the software load is complete:

Installing additional cluster rpms

	Important: After the software load is complete, ensure that the DVD is ejected from the drive before continuing. On systems with a retractable DVD device, you must remove the installation DVD before the system reboots. If you do not remove the DVD, a second installation process is initiated from the DVD when the system reboots. If a second installation process is started, halt the process and remove the DVD. Upon reboot, the system will boot from the original, completed installation (assuming that the second installation had not begun).

Do not press any keys while the system is coming up and while the new kernel boots. Ignore the Welcome to Kudzu utility. Do not press any keys until the login screen is displayed.

Log in as the root user when the login screen is displayed, and enter the root password you previously defined during the software installation process.
