Let's go to the controlling server where the PowerSmart tool is installed and take a look at the configuration
PowerSmart for XenApp (formerly Presentation Server) installs a windows service on the controlling server which is kept running.
Configurations are stored in two files in the installation directory
config.xml stores such information as idle management time period, XenApp servers to be controlled etc.
In this setup, between 5:00PM to 7:00AM and all days on weekends, the XenApp server hpilo2 will be shut down when there is no active or disconnected ICA sessions
Because we are using HP ILO2, the ILO IP address is specified as an attribute of the server hpilo2
CpsPowerMgrService.exe.config contains configurations such as how to power on/off servers and debugging configuration etc.
In this setup, HPPowerOn.cmd and HPPowerOff.cmd are going to be called to power on/off servers
The power on and off scripts contain simple winrm based commands. They take ILO address as parameter. You may need to customize these scripts to suit your environment
Now let's change the clock to simulate what will happen when night comes
Because there is no connection to hpilo2, hpilo2 should be powered off. The events should be logged in eventlog.
Let's switch to hpilo2 console to confirm
Now let's change the time back, it is time to go to work
PowerSmart tool should power on hpilo2 server and power up event should be logged in event log
Let's switch to HPILO2 server console to confirm
