DAQ CRASH RECOVERY

Starting the MIDAS DAQ after Crash

1. Stop the DAQ frontend (exclamation mark). If you cannot stop it just close the terminal where the frontend lives.

   Login to mulandaq PC on account mulan
   
   Go to acquistion directory mulandaq/mulanfe
   
   cd mulandaq/mulanfe
   

2. Execute midas_cleanup

   ./midas_cleanup
   

3. Execute ramverify

   ./ramveryfy
   

   and make sure its output is OK (no errors). Here's an excerpt from a successful ramverify (errc=0).

   
   VME RAM VERIFICATION TESTS for 0xE0220000 started
   Writing  16384 ints = 0x55555555 from 0xE0220000
   Checking 16384 ints = 0x55555555 from 0xE0220000
   errc = 0
   End: Address 0xE022FFFF is 0x55555555
   Writing  16384 ints = 0xAAAAAAAA from 0xE0220000
   Checking 16384 ints = 0xAAAAAAAA from 0xE0220000
   errc = 0
   End: Address 0xE022FFFF is 0xAAAAAAAA
   Writing  16384 ints = 0xFFFFFFFF from 0xE0220000
   Checking 16384 ints = 0xFFFFFFFF from 0xE0220000
   errc = 0
   End: Address 0xE022FFFF is 0xFFFFFFFF
   Writing  16384 ints = 0x00000000 from 0xE0220000
   Checking 16384 ints = 0x00000000 from 0xE0220000
   errc = 0
   End: Address 0xE022FFFF is 0x00000000
   VME RAM VERIFICATION TESTS for 0xE0220000 finished
   

4. If ramverify fails, reboot the VME WFD crate

   ./reboot_vmecrate
   

   and redo ramverify

   Start a web browser http://mulandaq:8081
   
   If the web page is not coming, start the mhttpd by hand
   (midas_cleanup should have done it)
   mhttpd -p 8081 -D
   
   (If it refuses to run, just keep trying in approx 30 sec. intervals)
   
   Make sure that mlogger is running.
   If there's no mlogger (see the MIDAS web page)
   mlogger -D
   
   
   Start the MIDAS front-end
   ./fewfd
   
   
   Now you're ready to collect data
   

midas2root

Login to mulandaq PC with account mulan

Go to acquisition directory mulandaq/midas2root

cd midasdaq/midas2root

1. Run midas2root processor to create the .root files from the .mid files

   ./muroot
   

   Login to mulan1 PC with account mulan
   
   Go to directory kentucky/midas2root
   
   cd kentucky/midas2root
   

2. Start the second midas2root processor

   ./muroot
