Welcome to the Mac user DAQ wiki!

Mac OS updates

Remember to update the ssh_config file every time you upgrade your operating system.

sudo vi /etc/ssh/ssh_config

Before you tunneling to novadaq-near-gateway-02.fnal.gov

  • Check Connected servers.
    Click Finder->Settings->General->Connected servers

  • Choose a vncviewer.
    Tiger VNC never works on my mac.
    Real VNC works with minimal extra actions.
    Other APPs not even Tiger VNC level.

  • Make sure that in the 'System Settings'->'Privacy & Security'-> Accessibility, you allow the Real VNC to control your computer.

Power up DCMs.

The scripts to bring up high voltages on APDs is located on novadaq@novadaq-far-mgr-02, we can jump twice to connect it through novashift@nova-cr-01.

ssh -AKXY novashift@nova-cr-01
ssh -AKXY novadaq@novadaq-far-mgr-02

Try to ssh the DCM from the control room machine to see if it is down if we cannot confirm it from the CSS-GUI.

ksu novadaq
ssh root@dcm-1-02-03

Go to the directory where the scripts live.

cd /home/novadaq/Online/pkgs/PowerUtilities/scripts/

The DCM number range is from 1 to 12, 1 is the far end of the top modules, 6 is the near end of the top modules, and 12 is the most bottom one. For example, if we want to power up the top part of the FarDet. We can loop over the DCMs on each diblock.

for dcm in `seq 1 6` ; do DCM_On.sh 11 $dcm ; done

Sometimes, there will be some DCMs still in trouble, we should power cycle it by using DCM_Cycle.sh then type the diblock number and DCM number.

NOvA DocDB

Restart the spill server backbone

  • Check the SNEWS connections to novadaq-near-gateway-01,
  • If there is no SNEWS heartbeats and no long SNEWS trigger,
  • Try to login NearDet-1 on NOvA-CR-05, and restart the spill server backbone on the left menu, then there will be color cycled on the four boxes.
  • Remember to check the log file, to see if it is updating by ls -l.
