Managing HP Serviceguard A.11.20.20 for Linux, May 2013

6.1.4.48 pv
Physical volume on which persistent reservations (PR) will be made if the device supports it.
IMPORTANT: This parameter is for use only by HP partners, who should follow the instructions
in the package configuration file.
For information about Serviceguard's implementation of PR, see “About Persistent Reservations”
(page 72).
6.1.4.49 pev_
Specifies a package environment variable that can be passed to external_pre_script,
external_script, or both, by means of the cmgetpkgenv command. New for modular
packages.
The variable name must be in the form pev_<variable_name> and contain only alphanumeric
characters and underscores. The letters pev (upper-case or lower-case) followed by the underscore
(_) are required.
The variable name and value can each consist of a maximum of MAXPATHLEN characters (4096
on Linux systems).
You can define more than one variable. See “About External Scripts” (page 127), as well as the
comments in the configuration file, for more information.
6.1.4.50 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” (page 127), as well as the comments in the configuration file, for more
information and examples.
6.1.4.51 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” (page 127), as well as the comments in the configuration file, for more
information and examples. See also service_cmd (page 183).
6.1.4.52 user_host
The system from which a user specified by user_name (page 191) 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
