h1. Troubleshooting 

%{color:red} *Any time day or night, please call experts if you are in need of help and the answer is not provided below.*%

h2. *VNC Shared Desktop*

h3. Mouse clicks not working. Keyboard remapped. Arrow keys type numbers.

*Try this first*

Press the modifier keys one by one (Alt/Option, "Windows", Control or "Apple"/command, Alt/Option, Control) and see if this solves the problem. This has been suggested as a solution by various online forums, for when the keyboard is acting like a modifier key is stuck in VNC.

*Try this second* 

Kill synoptic, restart it.

Procedure: 

* Open a new terminal window on @lariat-cr-02@ (or log in remotely).

* Find the process ID's to kill by issuing the command 

<pre>ps aux | grep javaws</pre>

* The integer after @lariat@ is the process ID.  For example:

<pre>

[lariat@lariat-cr-02 ~]$ ps aux | grep javaws

</pre>

* Kill all of these processes: (you may ignore the one for your @grep@) 

<pre>kill -9 1319

kill -9 9599

kill -9 22629</pre>

* Check that your keyboard and mouse function are normal again. 

* Restart DAQ or Event Viewer if needed. THEN re-launch Synoptic.

*Try this third*

Ask on the hang-out if someone, via VNC, is able to use the keyboard ... sometimes it works.  

*Try this fourth*

Kill VNC. Restart it.

*'VNC server closed connection'* might mean that the vnc server on lariat-cr-02 is not running. 

Log on to lariat-cr-02 and check if the X11 vnc sever is running:

<pre>

$ ps aux | grep vnc 

lariat 31537 0.0 0.0 103308 860 pts/5 S+ 00:12 0:00 grep vnc 

</pre>

Re-launch it:

<pre>

[lariat@lariat-cr-02 ~]$ x11vnc -create -localhost -xinerama -display :0 -shared -alwaysshared -many -forever -bg -rfbauth ~/.x11vnc/passwd

</pre>

Check that it is running now:

<pre>

[lariat@lariat-cr-02 ~]$ ps aux | grep vnc

lariat 31670 8.4 1.6 194032 61944 ? Ss 00:14 0:10 x11vnc -create -localhost -xinerama -display :0 -shared -many -forever -bg -rfbauth /home/lariat/.x11vnc/passwd

lariat 31753 0.0 0.0 103308 860 pts/5 S+ 00:16 0:00 grep vnc

</pre>

...and shifter is able to connect (the most important part!)

*If nothing else works*

Someone has to go to ROC-w and hard reboot the PC...

h2. *Trigger and DAQ system*

When the DAQ crashes, please post the relevant information to [[DAQerrors]] for experts to study.

h2. *Common failures:*

*Communication failure with the front ends.* 

* Trying clearing it with 

<pre>lariatReset</pre>

or 

<pre>./lariat-online/daq/bin/lariatReset </pre>

Wait a few minutes and then try the @go 500@ command again.

*Unable to start a new run:* <pre>lost connection

Permission denied (gssapi-keyex,gssapi-with-mic)</pre>

* Log out of the DAQ machine, and use the command *@kticket@* to pick up a fresh kerberos ticket with the special principal that we use for the DAQ: @lariat/lariat@lariat-daq00.fnal.gov@FNAL.GOV@. Check for this success with @klist@. Then log back in to the DAQ machine and start a new run.

*Dies with* <pre>ERROR: ReadRegisgter ACQUISITION_STATUS CAEN_DGTZ_CommError BoardId 0</pre>  

* Wait 2 minutes, then try to start again.

* Try issuing the command @lariatReset 0 1@ waiting more then 5 seconds, and trying again.

This command is appropriate when one sees any type of "CAEN_DGTZ" error.  This command will NOT help the persistent ports error.

*DAQ fails with* <pre>Found persistent communication port still open</pre>

* Wait 8 minutes for the ports to clear, then try again.

*DAQ fails with* <pre>An exception occurred when trying to send a message to ..."</pre>

* Check that the terminal you are running the DAQ from is indeed lariat-daq00 (or a screen within it).  Output from @klist@ should show the default principal as "lariat/lariat/lariat-cr-02.fnal.gov@FNAL.GOV" or similar if running from a screen off lariat-daq00 from the ROC-West station.

*Run number fails to increment* or has reset to a low number such as 1: 

* Stop the run and then on the DAQ terminal edit @/opt/lariat-online/config/runNumber.dat@ to correct the run number. Start new run after.

h3. Run Status page not updating

* Try refreshing the page. 

* If the ACNET node has gone down (as in a power loss) may need to re-start the tomcat servlet: 

** @ssh tomcat@lariat-wbm.fnal.gov@, then @kitty@.  (Yep, "kitty.")

* If there are messages of lost connection and failed to copy run.xml.new : 

** kill the run (by hitting enter in the DAQ terminal), type the command "kticket" into the DAQ terminal, the start a new run by typing the command "go 500".

h3. LArIAT beam mode not automatically updating Beam / No Beam States

* Try restarting the script on an ACnet console, page D129

* Select the *Restart Persistent* option

!https://redmine.fnal.gov/redmine/attachments/download/40201/lazarusRising.png!

* From list of processes, select *LArIAT_beamCheck.acl*

!https://redmine.fnal.gov/redmine/attachments/download/40204/persistenceOfMemory.png!

* Confirm by clicking the *Restart* button

!https://redmine.fnal.gov/redmine/attachments/download/40203/puddnShang.png!

h3. Other failures: 

* If the DAQ is having trouble talking to the crates, try issuing the command @lariatReset 0 1@ waiting more then 5 seconds, and trying again.

This command is appropriate when one sees any type of "CAEN_DGTZ" error.  This command will NOT help the persistent ports error.

* *No triggers at all* If the trigger crate has been power cycled and the V1495 is not emitting triggers: [[Reset1495]]

h2. *Wire Chambers*

Nominal Voltages:

|_. WC1 | -2425 |

|_. WC2 | -2400 |

|_. WC3 | -2550 |

|_. WC4 | -2450 |

* If the wire chambers HV trips: *Wire Chamber voltage* "instructions to control wire chamber voltages":https://cdcvs.fnal.gov/redmine/projects/lariat-online/wiki/Using_Synoptic_for_monitoring#4-Synoptic-power-supplies-controls

* If the wire chambers are acting strangely: *Wire Chamber Electronics* "remote power cycling instructions":https://redmine.fnal.gov/redmine/projects/lariat-online/wiki/Communicating_with_the_wire_chambers including mini-DAQ and telnet interface.

* If the wire chamber system is skipping spill numbers, it may be a high trigger rate (> 30 k per spill).  The wire chamber controller may still be reading out the hits from the last spill.

h2. *High voltage for the wire chambers, TPC wireplane bias, cryo PMTs*

%{color:red}ICathode HV trips off due to LAr level interlock.%

[[Drift HV]] TPC Cathode Voltage

"*General Instructions for controls via Synoptic*":https://cdcvs.fnal.gov/redmine/projects/lariat-online/wiki/Using_Synoptic_for_monitoring#section-10

Also valid for some of the muon range stack paddles (1-8), the halo veto and 1 aerogel PMT.

*ONLY IF SYNOPTIC DOESN'T WORK* "Instructions for controls via ACNET":https://cdcvs.fnal.gov/redmine/projects/lariat-online/wiki/Using_ACNET_to_power_up_the_power_supplies

* The readback voltage doesn't make any sense, is of the wrong polarity and/or is way above the nominal value, but just for a fraction of time.

This is most likely just a glitch in the readout, please ignore if it happens once or twice. If it happens too frequently, set voltage to 0, turn off the power supply and report it. 

* The readback voltage doesn't make any sense, is of the wrong polarity and is way above the nominal value, and the value is stable~ish (you might see small fluctuations over time)

This is a typical symptom of a bad power supply. Try to set it back to 0, turn it off and disconnect the SHV cable. If the readout values remain the same, it confirms there is a hardware problem. Please contact Brian Fellenz for repairs if we don't have a spare for that unit.

FYI, the power supplies have a given voltage rating and cannot physically deliver voltages beyond that range. Also, their polarities cannot be swapped so if you see the wrong sign on the readout ie a positive voltage on a negative power supply or vice versa, then you can be sure the unit is broken or you have a problem somewhere else in the system.

- Bias voltage rating: - 500 V for the shield and induction planes, + 500 V for the collection plane.

- ELT and Hamamatsu PMTs: +2000 V

- Wire chambers: - 5000 V

- All of the other units: -2000 V

* Something went wrong during a ramp, I need to turn off the supply!

There is an interlock that prevents you from using the normal fast controls on the power supply when a ramp is on-going. First, *stop the ramp by clicking on the STOP button*. This will stop the ramp and clear the interlock. If you need to go back to 0 quickly, use the fast controls to set the voltage to 0 and *don't forget to turn off the supply!*

*Even if the controls appear not to respond, set the voltage to 0 and turn the supply off*. Contact Charlie Briegel first and describe the problem in detail. If you can and if it's safe, disconnect the SHV cable from the power supply. If the readback values remain the same, then the power supply is broken.

* *ACNET controls expert: Charles (Charlie) Briegel, x4510 briegel@fnal.gov*  

* *VME power supplies repairs / replacements: Brian Fellenz, x2512 fellenz@fnal.gov*

h2. *SiPM and ARAPUCA power supply*

A low-voltage power supply module on the MCenter control room racks is used to power SiPM boards and (as of Run III) the ARAPUCA light detection device.  

To turn it on:

# Switch on the supply

# Press "Output on/off" to turn on output

# Press "Voltage"

# Adjust to 24V using either the knob (left) or the number pad (right) 

!https://cdcvs.fnal.gov/redmine/attachments/download/39382/arapuca_supply.png!

h2. *Event Viewer*

* If the event viewer stops cycling through the events and the terminal from which it is running shows a list of lines saying something like _"event XX in file, but on event 0"_ with _XX_ any number,

** _*ctrl+z*_ 

** _*ps -def*_ to look at the processes list. Look for the job ID of the process _"python /lariat/app/users/EventViewer/..."_ 

** _*kill -9 JobID*_ to kill the event viewer

** open a new event viewer <pre>ssh lariat@lariatgpvm01.fnal.gov 

cd /lariat/app/users/EventViewer/; source SETUP_ONLINE_EVENTVIEWER.sh</pre>

* If the problem persists and/or become more frequent, exit the session you are in and try to connect from a different gpvm machine

h2. Power Cycle the ASICs (TPC Wire Noise)

* Anecdotal evidence has shown that analog noise on the TPC wire readout channels can be 

alleviated by power cycling the TPC electronics: ASICs and Warm Receiver/Drivers

* You can remotely power cycle the TPC electronics.  Log onto lariat-gateway00.fnal.gov with X-forwarding enabled, type "firefox", and go to http://lariat-pdu02.fnal.gov.  Usename "ftbf" (password posted on Post-It on side of ROC monitor, and whiteboard in MC7).  Choose the *CYCLE* option, which will automatically give a 60 second powerless interlude.

* Further important informations can be found on the white board in MC-CR.

* This mechanism is controlled by a smart power distribution unit (PDU) located under the 

TPC electronics power supply near the cryostat in the enclosure.   Due to electrical safety 

rules you must *NOT* use any of the other outlets on this PDU.  Do *NOT* remove the protective 

outlet covers at any time.

!https://redmine.fnal.gov/redmine/attachments/download/25467/lariat-pdu02-cycle.png!

h2. Power Cycle the pLAPPD V1742  (V1751 or V1742 readout hang ups)

Error looks like this:

<pre>*** Fatal error opening CAEN board at 3,0</pre>

* Most likely the V1742 has hung up and needs a power cycle.

* You can remotely power cycle the V1742 digitizers.  On a firefox on lariat-cr-01 or at MCenter, go to http://ftbf-pdu05.fnal.gov.  Usename "ftbf" (password posted on Post-It on side of ROC monitor, and whiteboard in MC7, or docdb 2187).  Choose the *CYCLE* option, which will automatically give a 30 second powerless interlude.

* This mechanism is controlled by a smart power distribution unit (PDU) located under pLAPPD readout 

crate near the beam line on the upstream side.

!https://redmine.fnal.gov/redmine/attachments/download/39804/pLAPPD_PDU.png!

h2. Recover from a LAr level interlock

Assuming the LAr Level dropped low enough to trip off the TPC Cathode power supply, and maybe you even powered down the PMTs.

# Be sure HV is set to zero for these: Cathode Drift, Wire Bias, cryo-PMTs

How to control the [[Drift HV]]

# Power down the ASICs. (They should be off when TPC voltages change.)

# Contact one of these people to [[Reset the HV LAr level interlock in IFIX]]

# Bring up the Cathode

# Bring up the Wire Bias

# Bring up the ASICs

# Bring up the PMTs

h2. DQM troubleshooting

If the DQM is %{color:red}flashing red%...

* Check to see if the DAQ is running. If it isn't running, you should start a new run!

* Check the "LArIAT Run Status page":http://lariat-wbm.fnal.gov/lariat/run-alert.html. If the number under *Complete Files Waiting* is greater than 10, please call a data handling expert!

* Check the disk space on the @/lariat/data@ mount with the command @df -h /lariat/data@ on a @lariatgpvm@ or @lariat-daq@ machine. If the disk space is 100% full, please call a DQM expert!

[[Some details of how DQM is set up]]

h2. PB S60 PPD Params

If F:MC7AN , F:MC7ANB and F:MC7ANP show the values 1  -6 (in red), this is probably a communication problem, where we are not receiving data from them.

Usually it comes back in a few minutes. 

If not, call the MCR and ask them if they can see those values.
