HP XC System Software Release Notes for Version 3.0

2 Important Release Information
This chapter contains information that is important to know for this release.
2.1 Firmware Revisions
The HP XC System Software is qualified against specific firmware revisions. Follow the
instructions in the accompanying HP Cluster Platform documents to ensure that all hardware
components are running the latest firmware version.
The master firmware list for this release is available on line at:
http://www.docs.hp.com/en/highperfcomp.html
The master firmware Web page lists the minimum firmware revisions on which the Version 3.0
HP XC System Software has been qualified. At a minimum, your HP XC system components
must be running these versions of the firmware.
Read the following information before upgrading the firmware on any component in your HP
XC system:
• It is possible that some minimum firmware revisions shown on this Web page are no longer
available because firmware revisions become obsolete when newer versions are released.
• New revisions of the firmware are supported and are expected to work, however, not all of
the new firmware revisions have been qualified on the HP XC software.
• There is always the possibility that changes in non-qualified firmware unintentionally
introduce regressions when being used with the HP XC software. It is possible that the
regression could cause anomalies in system operation. Report regressions in XC operation
that result from non-qualified firmware upgrades to the HP XC support team at
[e-mail]
• The Web page clearly indicates if newer versions of the firmware are known to be
incompatible. Do not install these newer firmware revisions because unexpected system
behavior might occur.
• Never downgrade to an older version of firmware unless you are specifically instructed to
do so by the HP XC Support team.
• Contact the HP XC Support team if you are not sure what to do regarding firmware revisions.
• If you find a regression or problem in a more recent version of firmware, contact the HP XC
Support team.
2.2 Patches
Software patches are available for this release, and you are required to download and install all
patches.
Because network connectivity is not established during a new installation until the cluster_prep
utility is run, you are instructed to download the patches when you reach that point in the
installation and configuration process. “Required Task: Install Software Patches” (page 32) and
the HP XC System Software Installation Guide provide more information.
