Distributed Systems Administration Utilities V1.9 Release Notes for HP-UX 11i v2 March 2008

1 Distributed Systems Administration Utilities V1.9 Release
Notes
Distributed Systems Administration Utilities provide several tools for simplifying the management
of groups of systems and Serviceguard clusters.
DSAU consists of three primary components:
• Configuration synchronization tools - provide policy-based configuration management for
groups of systems and Serviceguard clusters.
• Consolidated logging tools - provide centralized logging and advanced log filtering features.
Specific support is provided for creating a highly available log consolidation server using
Serviceguard.
• Command fanout tools - provide high performance tools for executing shell commands and
distributing files across groups of systems and Serviceguard clusters.
Each of these components is based on an open source product:
• Configuration synchronization uses the Configuration Engine (cfengine)
• Consolidated logging uses Syslog Next Generation (syslog-ng)
• Command fanout uses Parallel Distributed Shell (pdsh)
What's in This Version
The 1.9 version of DSAU supports cross-subnet Serviceguard configurations. The later sections
in this document discuss the details of this new feature. Table 1-1 lists the specific open source
versions included with this release of DSAU.

Configuration Synchronization
New Features
Configuring Synchronization Master (csync master) Server in Cross-Subnet Cluster
Environments
In a cluster environment, if all the nodes are within the same subnet, then a server within that
cluster environment can be configured as the csync master server.
However, in a cross-subnet cluster environment, the csync master server must be an external
system, preferably a quorum server, outside the cross-subnet cluster. A cross-subnet cluster can
be configured only as client, with an external system acting as the cfengine master. After an
external system is configured as the csync master, the cross-subnet cluster nodes can be configured
as cfengine managed clients.
