Usage
Invoke the script from the Powershell command and specify the configuration file and eventually if you run it in "check" mode.
It is recommended to execute the script interactively first using the check mode. Using this mode, only connection and remote commands doing simple display will be executed, no shutdown will be performed.
Use the script then it at your convenience from any utility (scheduler, backup agent, ...) to shutdown the virtual machine.
To display script help text, please use either this Windows command:
c:\Charon>powershell -file charon_vmshutdown.ps1 -help |
or the Powershell "get-help" command:
PS C:\Charon> get-help c:\charon\charon_vmshutdown.ps1 -full |
To restart the virtual machine, the automatic boot on restart has to be set at SRM level and the following Windows service command has to be used:
c:\Charon>sc start <servicename> |
Note on CHARON virtual machine service:
The 'expect' mode will perform the "power off" command itself or will send the "F6" key if this command is not available stopping then the service. Other modes will perform a clean shutdown without powering off the virtual machine, letting then the service active and the virtual machine at SRM prompt. This is why a loop is introduced to check the virtual machine is responding to "ping". Once it does not respond anymore, the script will wait for a specified amount of time (waitbeforestop parameter) before stopping the service.
