About Serviceguard Releases
Types of Releases and Patches
Versions of Serviceguard are provided as platform releases, feature releases, or patches.
Platform Release
A platform release is a stable version of Serviceguard, which is the preferred environment for the
majority of Serviceguard customers. Platform releases may also contain new Serviceguard features.
These releases are supported for an extended period of time, determined by HP. Patches will be
made available within the extended support time frame even though a newer version of Serviceguard
is available.
Serviceguard A.11.20 is a platform release.
NOTE: For compatibility information for this and earlier releases, see the Serviceguard
Compatibility and Feature Matrix at the address given under “Documents for This Version”
(page 34). See also “Compatibility Information and Installation Requirements” (page 35) in these
Release Notes.
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
