Start SVT DAQ VNC

From counting house as hpsrun (should already be done):

...

source /usr/clas12/release/1.4.0/slac_svt_new/V3.4.0/i86-linux-64/tools/envs-sdk.sh
 
examples:
cob_dump --all atca1  => dumps the RCE status (booted is 0xea)
cob_rce_reset atca1 ==> resets all the RCEs
cob_rce_reset atca1/1/0/2  ==> resets a particular dpm (in this case dpm1)
cob_cold_data_reset res


et atca1 ==> "power cycles" the RCEs (sometimes they do not come back up nicely so rce_reset might be needed after)

....


INFO : clonfarm2 go.....


...

/data/hps/slac_svt/
=> diskless is exported to the cobs via nfs (server hosted on clonfarm1, NFS has to be v2 !! important )
=> daq is exported to the cobs via nfs. Has been compiled on DTM1
=> server contains the current software installation


Start rogue servers

On clonfarm2 start the rogue server

...

python SvtCodaDummy.py --local --env JLAB


Taking a CODA run

Info

If opening the Rogue GUIs for the first time, make sure all of the FEBs are turned off. 

...

(minus) CODA run control should be running in a VNC on clondaq7.  If not, contact the DAQ expert.  


Online Monitoring

The online monitoring can be started by

...

Which is in the hpsrun user path.

DAQ known issues

We experience few issues with the DAQ infrastructure during run cycles. In particular, it's advised to reset the DPMs in these cases:

...

At this point, the FEBs and hybrids can be brought up via the medm GUIs.


Hall B run Database

This is the link to the Hall B run Database to find all the necessary run specifications

Coda / Rogue Errors

1) RssiContributor::acceptFrame[X]: error mistatch in batcher sequence 000000dc : 00000000

...

Fix: Recycle FEBs and run control


SVT Start-up Procedure

1) If it is running, kill Rogue by deleting the GUI SvtCodaRun.py that is running in hpsrun-clonfarm2 (TigerVNC window). If doesn't come down, ctrl+c on the terminal where rogue is running

...

12) If all the FEBs look good (green) and SVT bias is on, then CODA should be ready
for "Prestart" followed by "Go"

SVT Baseline/Threshold Procedure

There are two procedures to compute the baselines and thresholds for the HPS.
