HP XC System Software Administration Guide Version 3.2

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, when 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 the HP XC system, see “Supplementary Software Products” (page 22).
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 XC environment. In this case, HP
XC documentation supersedes information supplied by the third-party vendor. For links to
related third-party web addresses, see “Supplementary Software Products” (page 22).
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 addresses. For more information about obtaining documentation for standard Linux
administrative tasks and associated topics, see the list of web addresses and additional publications
provided in “Related Software Products and Additional Publications” (page 24).
Intended Audience
