Managing HP Serviceguard for Linux, Tenth Edition, September 2012

• If your package has relocatable IP addresses, enter the SUBNET if you want it to be
monitored (this means the package will stop if the subnet fails).
This must be a subnet that is already specified in the cluster configuration, and it
can be either an IPv4 or an IPv6 subnet. It must not be a link-local subnet (link-local
package IPs are not allowed). See monitored_subnet (page 212).
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 103) for more information.
See also “Stationary and Relocatable IP Addresses and Monitored Subnets”
(page 68) and monitored_subnet (page 212).
IMPORTANT: For cross-subnet configurations, see “Configuring Cross-Subnet
Failover” (page 279).
• If your package runs services, enter the SERVICE_NAME as described under
service_name (page 215) and values for SERVICE_FAIL_FAST_ENABLED as
described under service_fail_fast_enabled (page 217) and
SERVICE_HALT_TIMEOUT as described under service_halt_timeout
(page 217). 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 224), and “Controlling Access to the Cluster” (page 186), 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 210), and “About Package Dependencies” (page 130).
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.
