• HP Fabric Clustering System for InfiniBand

is supported with Serviceguard to be

used as cluster heartbeat and data networks using IPoIB.

• A new option for the cmviewcl command (-f line) creates output that is formatted to

be used by scripts. The easily parsed output from the command is a concise summary

of cluster objects and their status.

• Support for Distributed Systems Administration Utilities (DSAU)

features

including:

— configuration synchronization tools

— consolidated logging tools

— command fan-out tool

• The memory allocation for packages has changed. When you create the cluster,

Serviceguard now reserves enough memory for the maximum number of packages

supported. Previously, it allocated memory based on the value of

MAX_CONFIGURED_PACKAGES that was specified in the configuration file. In addition,

the default for the MAX_CONFIGURED_PACKAGES parameter has changed. The default

is now 150, the maximum that Serviceguard supports. Previously the default was 0,

so users had to set it before any packages could be configured.

Impact

• Operating System:

— Serviceguard A.11.17 has been tested with HP-UX 11iv2 September 2004 and

later.

•Security:

— Serviceguard A.11.17 has been tested with HP-UX 11i Security Containment.

— Serviceguard now incorporates the enhanced security that was initially released

as a patch to address Security Bulletin HPSBUX010980.

— Serviceguard now uses the identd daemon to enhance security.

Compatibility

Serviceguard 11.17 does not yet support VERITAS Cluster Volume Manager (CVM) 4.1.

Serviceguard’s new features do not impact product performance.
