To automatically restart the guest operating system running on the CHARON instance, the automatic boot on restart has to be set at SRM level and the following Windows service command must be executed:
c:\Charon>sc start <servicename> |
To tell the script how the shutdown will be performed, some parameters are necessary. They are defined in a configuration file that is described in the Configuration file settings chapter.
Note on CHARON instance service:
The 'expect' mode will perform the "power off" command itself or will send the "F6" key if this command is not available, thus stopping the service. The other modes will perform a clean shutdown without powering off the CHARON instance, thus leaving the service active and the instance at the SRM prompt. To recognize the completion of the shutdown process in this case, a loop has been introduced to check if the guest operating system running on the instance responds to "ping". Once it no longer responds, the script waits for a specified amount of time (waitbeforestop parameter) before stopping the service.
