Managing HP Serviceguard for Linux Ninth Edition, April 2009

IMPORTANT: Each subnet specified here must already be specified in the cluster
configuration file via the NETWORK_INTERFACE parameter and either the
HEARTBEAT_IP or STATIONARY_IP parameter. See “Cluster Configuration
Parameters ” (page 100) for more information.
See also “Stationary and Relocatable IP Addresses and Monitored Subnets”
(page 71) and monitored_subnet (page 204).
IMPORTANT: For cross-subnet configurations, see “Configuring Cross-Subnet
Failover” (page 259).
• If your package runs services, enter the SERVICE_NAME as described under
service_name (page 206) and values for SERVICE_FAIL_FAST_ENABLED as described
under service_fail_fast_enabled (page 208) and SERVICE_HALT_TIMEOUT as
described under service_halt_timeout (page 208). Enter a group of these three for
each service.
IMPORTANT: Note that the rules for valid SERVICE_NAMEs are more restrictive
as of Serviceguard A.11.18.
• ACCESS_CONTROL_POLICY. You can grant a non-root user PACKAGE_ADMIN
privileges for this package.
See the entries for user_name, user_host, and user_role user_name (page 213), and
“Controlling Access to the Cluster” (page 176), for more information.
• If the package will depend on another package, enter values for
DEPENDENCY_NAME, DEPENDENCY_CONDITION, and
DEPENDENCY_LOCATION.
For more information, see the corresponding parameter descriptions starting on
(page 202), and “About Package Dependencies” (page 121).
Creating the Package Control Script
For legacy packages, the package control script contains all the information necessary
to run all the services in the package, monitor them during operation, react to a failure,
and halt the package when necessary. You can use Serviceguard Manager, Serviceguard
commands, or a combination of both, to create or modify the package control script.
Each package must have a separate control script, which must be executable.
For security reasons, the control script must reside in a directory with the string
cmcluster in the path. The control script is placed in the package directory and is
given the same name as specified in the RUN_SCRIPT and HALT_SCRIPT parameters
in the package configuration file. The package control script template contains both
the run instructions and the halt instructions for the package. You can use a single
script for both run and halt operations, or, if you wish, you can create separate scripts.
