No upgrade path from HP XC System Software Version 1.0 to Version 3.0 is supported. To upgrade your
existing Version 1.0 HP XC system to Version 3.0, you must perform a new installation and system
configuration of your HP XC system.
If your system is currently running HP XC System Software Version 1.0, be aware that Version 3.0 offers
new and enhanced features, including a simplified network hierarchy, which requires different wiring for
nodes and different disk requirements. Consult the HP XC Hardware Preparation Guide for instructions on
rewiring your hardware.
Software Upgrade Overview
The XC software upgrade process begins on the head node and is based on the Kickstart automated
installation process; all tasks are performed by the root user on the head node. The XC DVD software
distribution contains a bootable image and an embedded ks_upgrade.cfg Kickstart upgrade file. You
access the Kickstart upgrade file on the DVD when the you enter the command to start the upgrade.
After the head node is upgraded, it represents the configuration from which all other nodes are upgraded.
Before you begin an upgrade, become familiar with the upgrade characteristics listed in Table 7-2.
