you should run cold_boot_test_for_changing_dfl_temp.pl when the
temperature of your dfl is changing, to study COMM failures.

Everything is done on ultuna1:
on all
gotoiceboot
dtsxall

FIRST YOU NEED TO MODIFY
/home/testdaq/cold_boot_test/list_of_doms_to_test.dat
so that the script only tries to test DOMs which are in your DFL
(ie dont do reboot COMM tests on the reference boards).
cd /home/testdaq/cold_boot_test
nohup cold_boot_test_for_changing_temp.pl&
           
this script directs its output to
/home/testdaq/cold_boot_test/reboot.dat
                                                                                 
                                                                
you can run cold_boot_test_for_stable_temp.pl if you want to
test COMMS over a small temperature range (this gradually heats up the
DOMs, so you start them off cold and then over about 6 hours they heat up
by about 10 degrees).

 Checking the results: on ultuna1, do:
cd /home/testdaq/cold_boot_test
uu-reboottester.sh reboot.dat
for each DOM you will get the maximum number of consecutive boot failures.


To end the test:
  ps -ef  |  grep cold
and kill the process that comes up, then do
