| + | ======= Turn on/off Mode3 Data collection ====== | ||
| + | * To start/stop mode3 data collection on the EPICS GUI page click the button Cluster. In the newly opened window click the button **2 only** for mode2 data only or the **2 and 3** for both mode2 and mode3 data. | ||
| + | * Alternatively in a terminal on a2.gam run the command **"caput Data_CS_Save2And3 0/1"** to turn mode3 collection off/on. | ||
| + | * After doing this the decomp scripts should be modified as running the syncrofix command could overwrite this. | ||
| + | * For GRETINA standalone the script to modify is is **grdecompSA.sh** and for GRETINA-S800, **grdecompParticleGamma.sh**. | ||
| + | * For both scripts change the line **"caput Data_CS_Save2And3 0/1"** to turn mode3 collection off/on | ||
| + | |||
| + | ======= 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| + | start run window is obsolete.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 is losing events. Check the network speed of spdaq32 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=spdaq32 - -all , if the free colum becomes zero, DAQ related people needs to be notified for diagnostics. | ||

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. | + | The first is the alarm script that talks to users.

| + | * 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. | ||
