This is a generic page that should give you some insight about the LUCI instrument. More information, and an observers troubleshooting page, can be found at the Science Operations web site.

Please remember that, at least where LUCI is concerned, when in doubt, it is better not to do than to do , as the consequences can be disastrous.
If in doubt please contact: Work Cell Email

The LUCI production environment

The LUCI instrumentation software runs at

The LUCI observer GUIs run on the obs#.mountain.lbto.org machines; see the Science Operations web site for more info.

To access the luci.luci.lbto.org machine directly, connect to the LUCI web server; all the functionality needed for observing and routine troubleshooting can be found there. If prompted for a username and password, use your LUCI engineering account information (assuming you have a LUCI engineering account; if you do not, and need one, please contact on of the people listed above).

Run the LUCI software

Requirements:

Running GEIRS

Typically, GEIRS is always running on the LUCI server, and is started or stopped by the Instrument Scientist or Software Support. However, should GEIRS need to be restarted, simply log into the noVNC tab in the LUCI web server, right click on the Desktop (or click on the IceWM menu at the lower left), select GEIRS 1 or 2, and select "Restart GEIRS 1" or "Restart GEIRS 2". If you wish to display the raw GEIRS output on the observer computer, simply type luci_geirs1 or luci_geirs2 on the command line.

Restarting the Telescope Service

See the wiki page about LUCI TelescopeService reconnection. The file ~/lcsp/config/TelescopeIceClient.config on the luci.luci.lbto.org server should never need to be edited except by the Instrument Speialist or Software Support.=

Starting or restarting the LUCI software

Typically, the LUCI software is always running on the LUCI server, and is started or stopped by the Instrument Scientist or Software Support. However, should the LUCI software need to be (re)started, simply log into the noVNC tab in the LUCI web server, where there should be a LUCI Management Console available (if there is not, right click on the Desktop and select "Start LMC"). Press "Refresh table" in the LMC. If the services are down, each listed service will have a red dot next to it. If it is running the dot will be green. If the software is not running, click on the "System status: Start" button at the top, this will start all systems. The GUI will briefly dissapear, then a splash window with startup status will appear. After the software is up the original gui will appear now, hopefully in green.

SUPPORT NOTES:
  • There is an automatic script which will check for duplicate processes, and sends email if it finds any. If it finds duplicate processes, contact the Software Support.
  • The "Supervisor" service is not running, ever.

Shutting down the LUCI software

Steps to follow before you shutdown the software:
  • make sure there are no masks in Turnout!

Initializing the Instruments

  • Start an Observer GUI by typing the command luci_observer or just luci (which will also start a Telescope GUI).
  • In the Observer GUI click on the "LUCI 1" and "LUCI 2" buttons, and the instrument GUIs will open.
  • In the instrument GUIs click the top bar, which says: "Initialize" then select "ALL_UNITS". This is enough to initialize the instrument. No need to click on the "Submit" button.
