+  * {{ :daq:ulm-e16011_names.png?linkonly |S800 Trigger GUI}}
+======= Troubleshoot ======
+  * S800-Gretina not correlated: Check CC setfile ~s800/converged_daq/Scripts/CC0105Begin.tcl for extsynch and extclock
+  * S800 is losing events. Check the network speed of spdaq45 by /sbin/ethtool eth0 and /sbin/ethtool eth1 , both should show speed as 1000Mb/s, if one shows 100Mb/s then the network is too slow and S800 cannot send data to GEB fast enough which will cause event loss happen.
+  * Check the ringbuffer status, $DAQBIN/ringbuffer status --host=spdaq45 --all , if the free colum becomes zero, DAQ related people needs to be notified for diagnostics.

+  * Validation/Trigger window width is set by Dig116_CS_X55WidthP, Dig116_CS_X55WidthN. N/P stands for positive/negative maximum difference relative to Trigger timestamp which will be read out.
+  * Bringing up just the EPICs screen: in gretina home **./startGRETINA_EPICSdisplay**
+  * Set trigger multiplicity: **caput Trig0_CS_FSCThr n** (n=0,1,2,3... for mult 1,2,3,4...)
+  * See trigger pulse width: **CheckLED.sh**
+  * Change trigger pulse width: **SETLEDWIN <# of 20ns ticks>**
+  * Check timestamps, report boards that are out-of-sync: **CheckTS**
+  * Force timestamps to reset, DO NOT USE DURING RUN!!!: **SINGLEIMPSYNC**
+  * Warning script: run on a2 as gretina in ~/scripts: **./warningMessage4.sh **
+  * Check decomp stats  ** recordDecomp.sh | head -n50 **
+  * [[Flash digitizer firmware]]
+  * Check digitizer firmware version: on a2 or a1 terminal, type: **DIGSNIDFW** ,all digitizers should have same version firmware
+  * [[Replace digitizer with different color ones]]
+  * [[Replace fuses of digitizer]]
+  * [[No valid decomposed events]]
+  * Verify connecedt digitizers, at IOC interface, type **dbior**, it will print all identified digitizers within one bank
+  * VME related scripts are located at /global/devel/boot/vmeArray
+  * Check connected PVs, at IOC interface, type "casr"
-==== File Structure on GRETINA cluster / files to be kept ====
+====== Reboot a2 ======
+  * If a2 is rebooted due to system failure, two scripts need to be brought up
+    * from ~gretina: nohup scripts/warningMessage4.sh &
+    * from ~gretina/scripts/watcherdir: nohup watcher &
+ The first is the alarm script that talks to users.  The second is responsible for two things: writing record{Counters,Decomp,Settings} in the current run directory and cleaning up cluster process issues (usually restarting broken processes) soon after starting or stopping runs.
-   Here offline decomp data gets stored:
+  * Switch to a1
-    /global/data1a/gretina/user1
+    * If a2 cannot be brought back. Gretina DAQ can still run on a1. In the file ~/.profile , environment variable **DAQSERVER** needs changed to be a1.gam . This parameter is used to restrict gretina daq critical scripts to run on specific machine.

-====== Configuration files for decompostion ======
-The configuration for the decomposition is here: https://wikihost.nscl.msu.edu/gretina/doku.php/daq:decomp
-====== Positioning of the quads ======
-When a position of a detector is changed the following has to be updated:
-  * CS_DataId in https://wikihost.nscl.msu.edu/gretina/doku.php/daq:decomp
-  * CS_GblId in /global/devel/boot/vmeArray/vme*.cmd --- The Id is given by  hole_number * 16 + position_in_quad * 4 + board_number
-  * GTSort_shack/DetNum.dat --- self explanatory
