Managing HP Serviceguard for Linux Ninth Edition, April 2009

NOTE: If the package halt function fails with “exit 1”, Serviceguard does not halt
the node, but sets no_restart for the package, which disables package switching,
setting auto_run (page 198) to no and thereby preventing the package from starting on
any adoptive node.
Setting node_fail_fast_enabled to yes prevents Serviceguard from repeatedly trying (and
failing) to start the package on the same node.
For system multi-node packages, node_fail_fast_enabled must be set to yes.
run_script_timeout
The amount of time, in seconds, allowed for the package to start; or no_timeout. The
default is no_timeout. The maximum is 4294.
If the package does not complete its startup in the time specified by run_script_timeout,
Serviceguard will terminate it and prevent it from switching to another node. In this
case, if node_fail_fast_enabled is set to yes, the node will be halted (rebooted).
If no timeout is specified (no_timeout), Serviceguard will wait indefinitely for the
package to start.
If a timeout occurs:
• Switching will be disabled.
• The current node will be disabled from running the package.
NOTE: If no_timeout is specified, and the script hangs, or takes a very long time
to complete, during the validation step (cmcheckconf (1m)), cmcheckconf will
wait 20 minutes to allow the validation to complete before giving up.
halt_script_timeout
The amount of time, in seconds, allowed for the package to halt; or no_timeout. The
default is no_timeout. The maximum is 4294.
If the package’s halt process does not complete in the time specified by
halt_script_timeout, Serviceguard will terminate the package and prevent it from
switching to another node. In this case, if node_fail_fast_enabled (page 198) is set to yes,
the node will be halted (reboot).
If a halt_script_timeout is specified, it should be greater than the sum of all the values
set for service_halt_timeout (page 208) for this package.
If a timeout occurs:
• Switching will be disabled.
• The current node will be disabled from running the package.
If a halt-script timeout occurs, you may need to perform manual cleanup. See Chapter 8:
“Troubleshooting Your Cluster” (page 271).
