You can modify these values after the installation process is complete by using standard Linux system
administration procedures.
2.1.4 Default File System Layout and Disk Partition Sizes
Table 2-3 lists the default file system layout that is applied to the head node system disk. Because total
disk size may vary, partition sizes are shown as a percentage of total disk size. The HP XC System Software
Administration Guide describes the purpose and content of each file system.
Table 2-3 Default Disk Partition Layout on the Head Node

1 6 GB is subtracted from the total disk space, and space for all other file systems is calculated from the remaining disk space.
The default disk partition layout for client nodes (that is, nodes other than the head node) is listed in
Table 3-6 (page 64).
2.2 Task 1: Gather Information Required for the Installation
Before beginning the installation, read through the following items to make sure you are prepared to
supply the information required by the installation process.
1. Ensure that you have performed all preinstallation tasks described in “Preparing for a New
Installation” (page 23), especially the hardware preparation tasks.
2. Know how to use a text editor (such as vi, emacs, or gedit) because at some points in the system
installation and configuration process, you are required to modify text files.
3. Know the chip architecture for the HP Cluster Platform, which is listed in Table 2-4.
Table 2-4 Chip Architecture by Cluster Platform
Chip ArchitectureCluster Platform Model
Intel Xeon with EM64TCluster Platform 3000 (CP3000)
Intel Xeon with EM64TCluster Platform 3000BL (HP server blades)
AMD OpteronCluster Platform 4000 (CP4000)
Intel Itanium 2Cluster Platform 6000 (CP6000)
4. Ensure that you have in your possession the DVD distribution media that is appropriate for the cluster
platform architecture. The XC System Software and the open source software source code DVDs are
included in the architecture-specific media kits that were shipped to you.
5. Be prepared to supply the information listed in Table 2-5 during the Kickstart installation session.
