HP XC System Software Administration Guide Version 3.0

About This Document
This document describes the procedures and tools that are required to maintain the HP XC system. It provides
an overview of the administrative environment and describes administration tasks, node maintenance tasks,
Load Sharing Facility (LSF®) administration tasks, and troubleshooting information.
An HP XC system is integrated with several open source software components. Some open source software
components are being used for underlying technology, and their deployment is transparent. Some open
source software components require user-level documentation, specific to HP XC systems, and that kind of
information is included in this document, if required.
HP relies on the documentation provided by the open source developers to supply the information you need
to use their product. For links to open source software documentation for products that are integrated with
your HP XC system, see “Supplementary Information” (page 17).
Documentation for third-party hardware and software components that are supported on the HP XC system
is supplied by the third-party vendor. However, information about the operation of third-party software is
included in this document if the functionality of the third-party component differs from standard behavior
when used in the HP XC environment. In this case, HP XC documentation supersedes information supplied
by the third-party vendor. For links to related third-party Web sites, see “Supplementary Information”
(page 17).
Standard Linux® administrative tasks or the functions provided by standard Linux tools and commands are
documented in commercially available Linux reference manuals and on various Web sites. For more
information about obtaining documentation for standard Linux administrative tasks and associated topics,
see the list of Web sites and additional publications provided in “Related Information” (page 19).
Intended Audience
This document is intended for experienced Linux and LSF system administrators who already know how to
perform standard administrative tasks and who are also familiar with the HP XC system architecture,
components, and concepts.
