Info
titleNote for Red Hat Enterprise Linux/CentOS 7 .x and CentOS 7.xand 8

If your application and server need time to shutdown, it could be necessary to give more time in the service definition to prevent from the service stop procedure to fail due to timeout.

To do so, open the "Manage 'systemd' services" option and edit the service configuration file. You can then add the TimeoutStopSec= parameter in the Service section. This value is set to 20 minutes by default.

Example:

[Service]
...
TimeoutStopSec=3min

(info) More information can be found using the "# man systemd.service" command on your Linux server

...

When the script is initialized using option 6 or when a new virtual machine is added, the following lines are added:

...

case "$1"
in
  <configuration file>)
    #-- Uncomment and complete one of the following lines:
    #${CHARONDIR}/utils/charon_gstop_expect \$1 \$2 root <password> "<prompt>" <TRU64/VMS>
    #${CHARONDIR}/utils/charon_gstop_rsh \$1 \$2 <hostname> <TRU64/VMS>
    #${CHARONDIR}/utils/charon_gstop_ssh \$1 \$2 <hostname> <TRU64/VMS>
    #/<path>/<myscript>
  ;;

One of the blue colored lines above has to be uncommented depending on the method chosen. Other lines can remain in the script or can be deleted.

Whatever the shutdown script execution result is, the stop request sent by the systemctl command will stop the emulator. It is very important then to ensure the stop script has been tested and validated.

  • Check the guest can be reached via ping, if yes:

    • Issue the shutdown command via "rsh" (depends on the operating system),

    • Wait for a few seconds

    • Check if the guest can be "pinged" and repeat with an interval of 5 seconds

    • If the guest cannot be pinged, assume the shutdown procedure is complete

  • Kill the emulator process (Red Hat Enterprise Linux 6.x) or use the service kill command (RHEL/CentOS 7 .x and CentOS 7.xand 8). (question) The shutdown commands does not power off nor stop the emulator process, that's why this operation is needed

  • Report the stop information within the guest log file
