Running the Left-HRS DAQ
From Hall A Wiki
Revision as of 15:03, 2 August 2021 by Rom
Currently we can only run the DAQ in a standalone configuration. Eventually, we will connect it to the SBS DAQ.
update: June 7, 2021
Where to run: adev account on adaq1
I. Is the L-HRS DAQ already running ? Find the rcgui and use the buttons at the top. It's a standard CODA 3.10 GUI. If you let the mouse hover over the button for a moment, a little text box pops up, telling you what the button means. In smooth operation you are simply starting and stopping runs, so your favorite buttons would be Start (a double-triangle icon) and End (a box icon). II. DAQ not running ? How to bring the Left HRS DAQ up from scratch. If problems, see III and IV below. 2. Type "setupxterms", this pops up 4 xterms where you login to the 4 crates. I usually to do this from adaq2 because kcoda kills xterms. 3. In each xterm or window, login. Note, we use the adev account ! The old TS is not used in the DAQ; however, it does contain scalers which are read for xscaler and for event type 140 insertions. Available crates and how to login VXS crate with FADC ..... ssh -X halladaq8 -l adev lower fastbus crate ..... ssh -X lhrsfb1 -l adev middle fastbus crate .... ssh -X src2 -l adev uppper fastbus crate .... ssh -X lhrsfb2 -l adev If you don't know the password, text Bob 4. Startcoda (on adaq1 as "adev") by typing "startcoda" 5. In each window (step 3) type the appropriate "startrocN" command ROC1-hallada8: ./startroc1 ROC2-lhrsfb1: ./startroc2 ROC3-src2: ./startroc3 ROC4-lhrsfb2 : ./startroc4 You should see the ROCs connect in the red gui (platform). 6. Now in Run Control GUI (aka rcgui) Control(upper left)-> Connect -> click the tools thingy (Configure). Sometimes one component is disconnected or has a problem (red), like "configuring" instead of "configured". Often a reset ( <| in gui ) does the trick, and download again. Otherwise patiently start at 1. It works eventually. Assuming you can see connected ROCs in the rcgui: Next, Download, StartRun. If you don't know what a button means, let the mouse hover over it for a few sec. Configs to use. Note, the last correctly-running config is what gets loaded by default. You have two configs to pick: LHRS -- all 4 crates LHRS_FADC -- just the FADC, good choice if Fastbus is down and you don't need Fastbus ----------------------------------------------------- III. Trouble shooting Might need to power-cycle the crate if you see things like this: ./startroc1: line 2: 31770 Segmentation fault Old ROC processes can cause trouble. Kill them or reboot. ps awx | grep roc 21353 ? Sl 0:00 coda_roc -type ROC -name ROC3s 21394 ? Rl 44:36 coda_roc -type ROC -name ROC3 21477 pts/0 R+ 0:00 grep roc [root@src2 ~]# kill -9 21353 21394 Some other component not working (e.g. PEB error). Be patient, go to I.1 above. IV. Power cycling can be done remotely. ROC1 (formerly ROC31 during PREX) FADC crate go to bbvme1.jlab.org on firefox on a-onl@aonl1. (private/private) For the Fastbus, the hall A Tools screen and "Crate resets" used to work, but during the shutdown I have had trouble finding it.
