+ | * 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. | ||

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

+ | * 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. |
