| + | ======= New in 2022 ====== | ||
| + | start run window is obsolete. Two scripts are available for changing the data directory. Daq needs to be stopped, directories need to exist: | ||
| + | * changeDataDir_maintainRunNum <data dir> : keeps the Run number the same, for when we need to move physics experiment data collection to another disk | ||
| + | * changeDataDir_resetRunNum <data dir> : finds the lowest available Run number without any larger RunDir #s | ||

| * S800-Gretina not correlated: Check CC setfile ~s800/converged_daq/Scripts/CC0105Begin.tcl for extsynch and extclock | * S800-Gretina not correlated: Check CC setfile ~s800/converged_daq/Scripts/CC0105Begin.tcl for extsynch and extclock | ||
| + | * S800 is losing events. Check the network speed of spdaq45 by /sbin/ethtool eth0 and /sbin/ethtool eth1 , both should show speed as 1000Mb/s, if one shows 100Mb/s then the network is too slow and S800 cannot send data to GEB fast enough which will cause event loss happen. | ||
| + | * Check the ringbuffer status, $DAQBIN/ringbuffer status - -host=spdaq45 - -all , if the free colum becomes zero, DAQ related people needs to be notified for diagnostics. | ||

| * Warning script: run on a2 as gretina in ~/scripts: **./warningMessage4.sh ** | * Warning script: run on a2 as gretina in ~/scripts: **./warningMessage4.sh ** | ||
| * Check decomp stats ** recordDecomp.sh | head -n50 ** | * Check decomp stats ** recordDecomp.sh | head -n50 ** | ||
| + | * [[Flash digitizer firmware]] | ||
| + | * Check digitizer firmware version: on a2 or a1 terminal, type: **DIGSNIDFW** ,all digitizers should have same version firmware | ||
| + | * [[Replace digitizer with different color ones]] | ||
| + | * [[Replace fuses of digitizer]] | ||
| + | * [[No valid decomposed events]] | ||
| + | * Verify connecedt digitizers, at IOC interface, type **dbior**, it will print all identified digitizers within one bank | ||
| + | * VME related scripts are located at /global/devel/boot/vmeArray | ||
| + | * Check connected PVs, at IOC interface, type "casr" | ||
| + | * [[ Move detectors to new Hole position ]] | ||
| + | |||
| + | ====== 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. | ||
