Configuring Packages and Their Services
Choosing Package Modules
Chapter 6 215
external_pre_script
The full pathname of an external script to be executed before volume
groups and disk groups are activated during package startup, and after
they have been deactivated during package shutdown; that is, effectively
the first step in package startup and last step in package shutdown. New
for modular packages.
If more than one external_pre_script is specified, the scripts will be
executed on package startup in the order they are entered into the
package configuration file, and in the reverse order during package
shutdown.
See “About External Scripts” on page 122, as well as the comments in the
configuration file, for more information and examples.
external_script
The full pathname of an external script. This script is often the means of
launching and halting the application that constitutes the main function
of the package. New for modular packages.
The script is executed on package startup after volume groups and file
systems are activated and IP addresses are assigned, but before services
are started; and during package shutdown after services are halted but
before IP addresses are removed and volume groups and file systems
deactivated.
If more than one external_script is specified, the scripts will be
executed on package startup in the order they are entered into this file,
and in the reverse order during package shutdown.
See “About External Scripts” on page 122, as well as the comments in the
configuration file, for more information and examples.
user_host
The system from which a user specified by user_name can execute
package-administration commands.
Legal values are any_serviceguard_node, or cluster_member_node, or
a specific cluster node. If you specify a specific node it must be the official
hostname (the hostname portion, and only the hostname portion, of the
fully qualified domain name). As with user_name, be careful to spell the
keywords exactly as given.
