NODE_FAIL_FAST_ENABLED
If this parameter is set to YES and one of the following
events occurs, Serviceguard will issue a TOC (system
reset) on the node where the control script fails:
• 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
NOTE If the package halt script fails with “exit 1”,
Serviceguard does not halt the node, but sets
NO_RESTART for the package, which disables package
switching (AUTO_RUN), thereby preventing the package
from starting on any adoptive node.
Possible values are YES and NO.
The default is Disabled, not checked in Serviceguard
Manager, or NO in the ASCII file.
RUN_SCRIPT and HALT_SCRIPT
Enter the full pathname of the package control script.
These are two separate parameters: RUN_SCRIPT and
HALT_SCRIPT, allowing you to separate package run
instructions and package halt instructions into
separate scripts if you need to. In this case, make sure
you include identical configuration information (such
as node names, IP addresses, etc.) in both scripts.
In most cases, though, HP recommends that you use
the same script for both run and halt instructions.
(When the package starts, the script is passed the
parameter start; when it halts, it is passed the
parameter stop.)
