| + | |
| − | Where to run: adev account on adaq1.
| + | |
| − | | + | |
| − | I. Bringing the DAQ up from scratch.
| + | |
| − | | + | |
| − | 1a. Might need to reboot crates, but probably NOT.
| + | |
| − | 1b. Might want to kcoda, although startcoda does that.
| + | |
| − | | + | |
| − | 2. Type "setupxterms", this pops up 4 xterms
| + | |
| − | | + | |
| − | Might be a good idea to do it from adaq2 because kcoda kills xterms.
| + | |
| − | Alternatively you can do the commands in #3 by hand in windows.
| + | |
| − | | + | |
| − | 3. In each xterm or window, login. Note, we now use adev !!
| + | |
| − | | + | |
| − | The old TS is not used in the DAQ; however, it houses scalers
| + | |
| − | which are read for xscaler and the usual event type 140 insertions.
| + | |
| − | | + | |
| − | 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 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
| + | |
| − | | + | |
| − | ---------------------------------------------------
| + | |
| − | | + | |
| − | II. If CODA running somewhere and you just want to start/stop runs.
| + | |
| − | | + | |
| − | Type "rcgui" and start with point 6 above.
| + | |
| − | | + | |
| − | -----------------------------------------------------
| + | |
| − | | + | |
| − | II. Trouble shooting
| + | |
| − | | + | |
| − | Might need to power-cycle the crate if you 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.
| + | |
| − | | + | |
| − | III. Power cycling can be done remotely.
| + | |
| − | | + | |
| − | ROC1 (formerly ROC31 during PREX) FADC crate
| + | |
| − | go to bbvme1.jlab.org on firefox on a-onl@aonl1
| + | |
| − | | + | |
| − | For the Fastbus, the hall A Tools screen and "Crate resets"
| + | |
| − | used to work, but during the shutdown I have had trouble finding it.
