ISC end station upgrade RCG2.8.7:Rolf, Daniel, Jim, Dave
Rolf released the EXC code fix as RCG tag-2.8.7. The fix was tested yesterday on the DTS using Daniel's new Integrator Filter Module parts (IFM). Today I installed tag-2.8.7 on H1 and set the release/ pointers to refer to it. Daniel performed model cleanup and bug fixing of h1iscex and h1iscey during the morning, building against 2.8.7. We restarted these models several times today, with attendent DAQ restarts. After the final code change and restart, I repointed the release/ pointers back to RCG-2.8.5.
Daniel confirms the new RCG fixes the EXC and TP problems he was seeing with the IFM parts in the ISC end station models. This closes WP #4984
Power Down h1susquadtst: Jim, Dave
I took the h1susquadtst models out of the DAQ and we powered the front end down. Unfortunately this caused DAQ data errors for many front end systems for several minutes (susauxb123, lsc, asc, oaf in the corner station. all models in the mid and end stations). We tried a streamers restart on an end station sus model, which did not do anything. We then powered h1susquadtst back on and all the errors went away. I had forgotten to remove this system from the rtsystab file which may have caused the problem. After removing from both the DAQ and rtsystab, this time we issued a powerdown command and the DAQ problems were not repeated. To complete the power down of the LVEA test racks, all DC power supplies were powered off, as were the network switches. All power cords were removed from the FE computers.
EX Beckhoff h1ecatx1, Tuesday Freeze Up: Daniel, Dave
The EX Beckhoff system froze up at 13:50 PST. A repeat of its periodic Tuesday problems. Daniel restarted the system, but reported an unclean EPICS IOC startup (started too fast). Both conlog and the DAQ EDCU showed problems reconnecting to many h1ecatx1 channels. The problem was resolved after the EPICS gateway h1slow-h1fe was restarted, but even then it took about 10 minutes for conlog and EDCU to complete the reconnection in fits and starts.
Conlog reconfiguration: Dave
Following the ISC code changes, I reconfigured conlog. Later when conlog was not reconnecting to h1ecatx1, I added conlog's own epics channels to conlog to force a reconfiguration to hopefully permit a reconnection (this did not work, the epics gateway restart was the actual fix).
Partial and Modified-but-not-loaded Filter Module Files Loaded onto Front Ends: Jim, Dave
We performed the Tuesday reload of filter module files which had either been partially loaded or modified and not loaded over the course of the past week.
Modified files which were not loaded: ISIBS, SUSPRM, SUSPR3
Partially loaded files: SUSSR2, SUSSR3, SUSITMY, SUSBS, LSC, ASC, ASC-IMC, ISIHAM4, SUSETMX
SVN code with local SVN modifications: Dave
Attached is the list of FE user source code with outstanding local mods in SVN. Also listed, that for the guardian nodes source files.
