Managing Serviceguard 11th Edition, Version A.11.16, Second Printing June 2004

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4164
If NODE_FAIL_FAST_ENABLED is set to YES, the node
where the package is running will be halted if one of
the following failures occurs:
• A package subnet fails and no backup network is
available
• An EMS resource fails
• The halt script does not exist
• Serviceguard is unable to execute the halt script
• The halt script or the run script times out
However, if the package halt script fails with “exit 1”,
Serviceguard does not halt the node, but sets
NO_RESTART for the package, which causes package
switching (AUTO_RUN) to be disabled, thereby
preventing the package from starting on any adoptive
node.
Controlscript pathname
Serviceguard Manager will automatically create and
maintain a control script if you use Guided Mode, the
Serviceguard Manager default. If you choose, you can
edit the control script yourself, and name your own
path. Once you leave Guided Mode, however,
Serviceguard Manager cannot update your script.
Enter the full pathname of the package control script.
(The script must reside in a directory that contains the
string “cmcluster.”) Ensure that this script is
executable. In the ASCII package configuration file,
this parameter maps to the two separate parameters
named RUN_SCRIPT and HALT_SCRIPT.
It is recommended that you use the same script as both
the run and halt script. This script will contain both
your package run instructions and your package halt
instructions. If you wish to separate the package run
instructions and package halt instructions into
separate scripts, the package configuration file allows
allows you to do this by naming two separate scripts.
However, under most conditions, it is simpler to use the
name of the single control script as the name of the
