• The control script will exit with status 1.
If the halt script timeout occurs, you may need to
perform manual cleanup. See “Package Control Script
Hangs or Failures” in Chapter 8.
SERVICE_NAME
Enter a unique name for each service. Define one
SERVICE_NAME entry for each service.You can configure
a maximum of 30 services per package. The service
name must not contain any of the following illegal
characters: space, slash (/), backslash (\), and asterisk
(*). All other characters are legal. The service name can
contain up to 39 bytes.
SERVICE_FAIL_FAST_ENABLED
Enter YES or NO for each service. This parameter
indicates whether or not the failure of a service results
in the failure of a node. If the parameter is set to
Enabled, in the event of a service failure, Serviceguard
will halt the node on which the service is running with
a TOC. (An attempt is first made to reboot the node
prior to the TOC.) The default is NO. Define one
SERVICE_FAIL_FAST_ENABLED entry for each service.
SERVICE_HALT_TIMEOUT
In the event of a service halt, Serviceguard will first
send out a SIGTERM signal to terminate the service. If
the process is not terminated, Serviceguard will wait
for the specified timeout before sending out the
SIGKILL signal to force process termination. Define
one SERVICE_HALT_TIMEOUT entry for each service.
Default is 300 seconds (5 minutes). The minimum is 1
second, and the maximum value is restricted only by
the UNIX parameter ULONG_MAX, for an absolute limit
of 4,294 seconds.
Define one SERVICE_HALT_TIMEOUT entry for each
service.
SUBNET Enter the IP subnets that are to be monitored for the
package, one per line.
