There are a few ways to reboot and reset LHRS/RHRS DAQ crates.

Quick Resets

Problems with CODA 2.6.1 can usually be solved with a simple Reset (<< in rcgui) or with a Cold Start. Call an expert if you are stuck. Do NOT waste an hour stuck on resets.

If you reboot the ROC, or if something on the workstation is hung up, try pushing the ”Reset” button in runcontrol (<<” in rcgui). Then Configure, Download, and Start a run as usual. If a “quick” reset doesn’t work, try a Cold Start (see below)

Rebooting a ROC

If a ROC seems to be hung up, you can reboot it. To do this follow these steps:

1. Type ”reboot” at the vxWorks prompt (− > reboot) in the ROC's xterm window.
   1. Another possibility is to type “ctrl-X” at the vxWorks prompt; this sometimes works when typing reboot does not work
2. Wait 2 minutes and telnet back in to verify its alive.

The name of the ROC computer is normally written in the name of the xterm (hallasfi1, hallasfi2, etc). Finally, if the above does not work one can gain access to the cpu and press the reset button (or use the remote crate resets below).

Special Note on ROC3/ROC1

If the LHRS (RHRS) crate is power cycled, the boot parameters for ROC3(ROC1) will need to be re-entered. The boot parameters are located in doc/vmeram g2p.doc and also on the g2p Wiki[[1]]. To change the boot parameters do the following:

1. Go to the vxWorks prompt for ROC3 and type ”c”.
2. This will allow you to enter the parameters, one line at a time.
3. When finished, type ”p” to print the boot parameters (and check that they are correct)
4. Type ”@” to reboot the ROC.

Cold Restarts (Starting CODA from scratch)

1. To perform a cold start of the processes on the Linux computer (adaql1 or adaql2), simply type “startcoda” on the a-onl account. This performs a “kcoda” for you, as well as starts all the components you need.
2. Eventually runcontrol (rcgui) will pop up.
   1. In runcontrol press the Platform button and then ”connect”.
   2. After “connect”, verify you have the correct session (LHRS/RHRS) and configuration (LHRSHAP/RHRSBUFF). Usually you will, but if not you’ll need to select the session and config.
   3. You may now do the “configure” by pressing the button with crossed screwdriver and wrench in the upper left corner. Be patient, configure takes awhile.
   4. Then you may download, which is the next button to the right, it looks like a tape drive.
   5. In general, the button names can be discovered by putting the mouse on it and letting it sit there for a few seconds; a small box appears with the name of the button.
      
   6. To start a run, press the >> button.
   7. To end a run press the square box that’s sorta in the middle.
   8. To reset, press the << button.
3. Start datamon by typing “datamon”

If you ever logout of the DAQ computer adaql1 or adaql2 or have rebooted it, here is how to restart the preferred setup. Login to the adaql1(adaql2) console as ”adaq” and then

ssh -l a-onl adaql1(adaql2) 

emacs /prescale/prescaleL(or)R.dat
