See if you can find the sys-suspend command alanc mentioned above (test it out on another system if possible).
Alternatively a workaround would be to do a 'ps -ef' listing on the currently running processes on the server. Shutdown, move and restart the system and compare the 'ps' output once you've restarted the server to make sure the same set of processes are running once more. (They will obviously be running under different process id's.)
For a more verbose listing of the full commands that are running you could do
which gives the full process command line with parameters and may be more helpful.
