HP Serviceguard Version A.11.18 Release Notes, September 2008

HP recommends setting this parameter to yes in Metrocluster installations using EMC
SRDF.
IMPORTANT: vxdisk scandisks can take a long time in the case of a large IO
subsystem.
New for modular packages as of the September 2008 Patch (page 13). Equivalent to
VXVM_DG_RETRY in the legacy package control script.
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.
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. For more information, see “About External
Scripts” in Chapter 4 of Managing Serviceguard, and the comments in the package
configuration file.
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).
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.
HP supplies a template for external scripts: $SGCONF/examples/
external_script.template.
For more information, see “About External Scripts” in Chapter 4 of Managing
Serviceguard, and the comments in the package configuration file.
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.
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.
