HP Serviceguard Version A.11.19 Release Notes, October 2009

NOTE: You are encouraged to move to the A.11.19 release. For compatibility
information for this and earlier releases, see the Serviceguard Compatibility and Feature
Matrix at http://www.docs.hp.com -> High Availability ->
Serviceguard -> Support Matrixes. See also “Compatibility Information and
Installation Requirements” (page 52) of this document.
Feature Release
A feature release contains new Serviceguard features. Feature releases are for customers
who want to use the latest features of Serviceguard. In general, feature releases will be
supported until a newer version of Serviceguard becomes available. In order to receive
fixes for any defects found in a feature release after a newer version is released, you
will need to upgrade to the newer, supported version.
Patch
A patch to a release may be issued in response to a critical business problem found by
a Serviceguard customer, or a patch may enable new features. (Such features do not
affect the running of an existing Serviceguard cluster until you activate them, for
example by reconfiguring the cluster or reworking a package.)
In the case of a patch, the following is guaranteed:
• Patch-specific release testing is performed before the patch is posted.
• Existing functionality, scripts, etc. will continue to operate without modification.
• All fixes from the previous patch are incorporated.
Certification testing for a patch is recommended only for those fixes that are important
to your specific installation, or for new features that you intend to use.
Supported Releases
For information about the support life of a given release and its compatibility with
versions of related products, see the Serviceguard Compatibility and Feature Matrix, on
docs.hp.com -> High Availability, under the heading Serviceguard ->
Support Matrixes.
Version Numbering
Serviceguard releases employ a version numbering string that helps you identify the
characteristics of the release. The version string has 4 parts:
• Alphabetic Prefix
• First Numeric Field
