WHAT TO DO WHEN LUMI DOES NOT SEND ANY DATA ON THE DISPLAY
----------------------------------------------------------

Normally if the LUMI detector is in the tunnel, then lumi 
information should show up in the graphs of the lumi display.
If this is not happening then most likely the program 
"ldread" on the VME CPU has crashed. Here is some instruction 
on how to restart it.


1. Telnet at luxury.desy.de (lumi,lumi)
2. Type "lumistat" => you should see at the bottom some rates 
   "received". If not there is a problem so you should continue 
   with 3.
3. CTRL-C to exit lumistat
4. Telnet at lunatic (from luxury), (lumi,lumi). This is the VME 
   CPU where the daq is running.
5. Type "daqps" => this gives a list of processes running and 
   not-running. If "ldread" is not running (look at the bottom to 
   find this out) then you must restart it.
6. Type "mbtool 1- flush" => this flushes the Memory Board buffers.
7. cd src/daq/
8. Type "prio 10 ldread &" => starts the daemon.
9. Exit from lunatic and then from luxury (before that you can test 
   with lumistat if data is being received or just look at the lumi
   display).

HOW TO RESTART LUMI DAQ
-----------------------

1. Telnet to luxury and from there to "lunatic" (see above).
2. Open another terminal and just login to "luxury".
3. On luxury: Type "lumi_stop_daq"
4. On lunatic:  "daqstop"
		"daqinit"
		"daqstart"
5. On luxury:	"lumi_start_daq"
6. On lunatic:  "shmon" => then check if "emptynum" is changing.
   If yes the CTRL-C and exit. If NO CTRL-C and start from 4 again.
