Managing HP Serviceguard for Linux, Tenth Edition, September 2012

(Access Control Policies) Specify three things for each policy: USER_NAME,
USER_HOST, and USER_ROLE. Policies set in the
configuration file of a cluster and its packages
must not be conflicting or redundant. For more
information, see “Controlling Access to the
Cluster” (page 186).
MAX_CONFIGURED_PACKAGES This parameter sets the maximum number of
packages that can be configured in the cluster.
The minimum value is 0, and the maximum value,
which is also the default, is 300.
Can be changed while the cluster is running.
Cluster Configuration: Next Step
When you are ready to configure the cluster, proceed to “Configuring the Cluster”
(page 179). If you find it useful to record your configuration ahead of time, use the Cluster
Configuration worksheet (page 325).
Package Configuration Planning
Planning for packages involves assembling information about each group of highly
available services.
NOTE: As of Serviceguard A.11.18, there is a new and simpler way to configure
packages. This method allows you to build packages from smaller modules, and eliminates
the separate package control script and the need to distribute it manually; see Chapter 6:
“Configuring Packages and Their Services ” (page 199), for complete instructions.
This manual refers to packages created by the newer method as modular packages, and
to packages created by the older method as legacy packages.
The discussion that follows assumes you will be using the modular method. For information
and instructions on creating and maintaining legacy packages, see “Configuring a
Legacy Package” (page 271).
The document Framework for HP Serviceguard Toolkits provides a a guide to integrating
an application with Serviceguard, and includes a suite of customizable scripts intended
for use with legacy packages. This document is included in the Serviceguard Developer’s
Toolbox, which you can download free of charge from
http://www.hp.com/go/softwaredepot.
NOTE: As of the date of this manual, the Framework for HP Serviceguard Toolkits deals
specifically with legacy packages.
