Background

This document describes the procedure for restarting the DEIMOS daemons. When time is not critical, the preferred method to completely reset the DEIMOS software system is to perform a reboot of the various computers. When speed is important, the following method will be faster since it does not require rebooting machines.

Procedure

Semi-automated Method

The daemon restart procedure has been scripted (except that numerous passwords must still be entered manually). To execute the script when logged in from a DEIMOS numbered account, go to the background menu and select

	DEIMOS Engineering > Restart Processes > All daemons (keamano/polo/roto)

Alternatively, when logged into polo, type:

	restart_all_daemons

and follow the instructions to restart daemons.

Manual Method

1. Shutdown GUIs.
   • From the pulldown menu, select DEIMOS Control Menu > Shutdown All DEIMOS GUIs.
   • Run the ctx command to verify that all DEIMOS GUIs are down.
2. Stop polo daemons.
   • Log into polo as user kics.
   • Stop polo daemons with this commands:

     	deimos stop daemons

3. Restart keamano/roto daemons.
   • Log into keamano as user kics.
   • Stop all daemons with these commands:

     	deirot stop
     	deifcs stop daemons
     	deimos stop daemons

   • Verify that daemons are gone by running the ctx command as user dmoseng (or other DEIMOS user account) on polo. It should show no daemons running.
   • As user kics on keamano, restart all daemons with these commands:

     	deimos start daemons
     	deifcs start daemons
     	deirot start

4. Restart polo daemons.
   • Log into polo as user kics.
