HP XC System Software Release Notes for Version 3.0

About This Document
This document contains release notes for HP XC System Software Version 3.0. This document
contains important information about firmware, software, or hardware that may affect your
system.
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”.
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”.
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”.
