+ | ====== Reboot a2 ====== | ||
+ | * If a2 is rebooted due to system failure, two scripts need to be brought up | ||
+ | * from ~gretina: nohup scripts/warningMessage4.sh & | ||
+ | * from ~gretina/scripts/watcherdir: nohup watcher & | ||
+ | The first is the alarm script that talks to users. The second is responsible for two things: writing record{Counters,Decomp,Settings} in the current run directory and cleaning up cluster process issues (usually restarting broken processes) soon after starting or stopping runs. | ||
+ | |||
+ | * Switch to a1 | ||
+ | * If a2 cannot be brought back. Gretina DAQ can still run on a1. In the file ~/.profile , environment variable **DAQSERVER** needs changed to be a1.gam . This parameter is used to restrict gretina daq critical scripts to run on specific machine. |
