Configuring Packages and Their Services
Choosing Package Modules
Chapter 6 307
fs_fsck_opt The fsck options for the file system specified by fs_name.
Using the -s (safe performance mode) option of fsck will improve
startup performance if the package uses a large number of file systems.
This parameter is in the package control script for legacy packages.
See the fsck (1m) manpage for more information.
pev_ Specifies a package environment variable that can be passed to an
external_pre_script, external_script, or both, by means of the
cmgetpkgenv (1m) 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 (1024 on HP-UX systems).
You can define more than one variable. See “About External Scripts” on
page 185, as well as the comments in the configuration file, for more
information.
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 this file,
and in the reverse order during package shutdown.
See “About External Scripts” on page 185, and 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.
