May 6, 2009 online meeting minutes

present: Sergey Boyarinov, Sergey Pozdnyakov

Current eg1dvcs run status was discussed:

- DAQ rate is about 6-7kHz and data rate 30-35MB/sec, livetime >85%

- recent changes in CLAS CODA helped to speedup crashes recovery, some issues still remains

- CAEN SY1527 HV status: 3 glued patch panels tests goes good, one panel is installed already in hvec2; 2 bad channels were discovered in 2 boards; CAEN said that we can move single channel mezzanine card from board to board, but calibration must be performed after that, will ask CAEN if it can be done at JLAB; problem with 16 boards in hvec1 still exist (board in slo 16 trippes after a while), 15 boards works but 16 does not, will report to CAEN, may try to reproduce in test setup

- EC sec5 HV problems were observed, still unclear what exactly happened, we are watching, can be Lecroy mainframe or board(s) or IOC

- roc_reboot set for DC1-DC4 and DC7-DC10, works fine

- ungated str7201 scaler was replaced in polar (bit 14 stuck sometimes), 1881 was replaced in DC11 (corrupted data on high rate about 10kHz), will go to repair

- new network equipment install: 10GBit cards in clondaq1 and clondaq2 (4Gbit/s saturates one core), 10GBits tranceivers in BigIron, still waiting for 1GBit tranceivers to finish the project

- new SILO is in use, so far so good; may think about coping with extension '.part' and rename when coping is done

- 'run_log_polar' table in clasprod database was restored from clasdb1, data from the first part of eg1dvcs was restored from ascii file written by pol target operators; currently it is updates automatically

- 'run_log_end' etc recovery procedure still under development; may run by cron job
