Shutting Down IRIS Host from the Operating System

Typically, IRIS is stopped only for maintenance reasons, such as before halting or rebooting the server.

  1. Login as radarop.
  2. In a terminal window, type: iris&

    The IRIS Menu opens.

  3. Connect to localhost, or to a configured radar hostname.
  4. To avoid interrupting the current radar measurement and creating an incomplete data file, finish the current measurement:
    1. On the Task Scheduler menu, select STOP (When Done) for all tasks.
    2. Wait until the tasks are finished and the Ingest Process status in the radar status screen changes to Idle.
  5. Open the radar status screen by selecting Menus > Radar Status from the upper menu bar.
  6. On the radar status screen, select Ingest Process to change the status field to Stopped.
  7. Set Radiate to Off/Off.
  8. Close the IRIS Menu bar.
  9. In the operating system prompt, type: 
    qiris
  10. If necessary, shutdown the server from the command line, by typing: 
    poweroff

IRIS goes through a shutdown procedure to leave the radar and antenna in a safe, non-operating state. IRIS clients are disconnected.
