Rebooting ATCA On-Line Computers

This document describes how to reboot operational computers at the ATCA

NOEL

On the NOEL console (in the Computer Room), If you need to shut NOEL down:

PERICLES

Pericles is the linux PC in the Control Room that is usually used to display the observing windows.
After powering up, you need to: To display NOEL displays, If NOEL has been booted, there are 5 processes that you have to start manually:
ProcessCommand
mp_server @at$run:start_mp_server - writes monitor point data
weather @at$run:start_weather - restarts comms with the weather station
lomon @at$run:start_lo_mon - restarts comms with the Phase Transfer PC (rt)
ds @at$run:start_ds - restarts comms with the Data Set in the PMON rack which is used to start and stop the generator
pntcom @at$run:install_pntcom - installs global common for reference pointing
If you need to create extra NOEL terminals: You will need log into CACCC to restart the Correlator processes. Run the appropriate processes in each window.

CACCC

CACCC is the linux PC in the screened room which controlls the corralator.
In the unlikely event that it needs to be rebooted, all you should need to do is let it boot.

CACOR

CACOR, the correlator GUI is displayed on PERICLES - to generate this:

ELLEN

ELLEN is a linux box in the screened room. (It is at the bottom machine in the rack under the computing work table in the north east corner of the correlator room)
After power failure, it should boot itself.
In general you require two ellen xterms on Pericles - to do this Two tasks are required to be running on ELLEN for observing: The atdaemon should be running once ellen has booted. You can ensure it is running by executing 'atdaemoncheck' in an ellen xterms. If it says 'No atdaemon is running' then you can restart the atdaemon by running the command 'atdaemonrestart'
A second xterm should run atcalegacyserver

RT

RT is the linux PC in the screened room that controls reads the does the Round Trip Phase measurements used in lomon
After the machine has booted,

Weather Station

CAWEATHR is a PC in the screened room that reads the weather station data and serves the information to the VAX.
If you need to restart it:
