This A.11.17 version of Serviceguard is a platform release. This release
contains new functionality, defect repairs and support for new hardware
configurations. Highlights of the release are as follows:
Serviceguard A.11.17 supports the same configurations as previous
versions.
The following features are new for Serviceguard A.11.17:
• Serviceguard A.11.17 has been tested with HP-UX 11i Security

• HP Fabric Clustering System for InfiniBand is supported with

• Serviceguard now uses the identd daemon to enhance security. For

MAX_CONFIGURED_PACKAGES parameter has changed. The
