CDS Maintenance Summary: Tuesday 16th May 2023

WP11185 DAQ Load IOP and SUSAUX models with "file recovered" messages

Dave:

For those SUSAUX systems which were pre-upgraded to RCG5.14 and have been showing "INI file recovered" messages after the main RCG upgrade, I did a manual DAQ Load to replace this message with today's date. No DAQ restart required.

WP11193 IO Chassis DC power disruption

Marc, Jeff, Corey, Erik, Dave:

To prepare for IO Chassis +24VDC power supply work, all models on h1omc0, h1lsc0 and h1asc0 were stopped and these three front-ends were fenced from the Dolphin fabric.

After the work was completed and the IO Chassis were powered back on, we rebooted these three machines (sudo systemctl reboot) to get them running again.

WP11195 Update H1EPICS_SDF.ini

Dave:

I regenerated H1EPICS_SDF.ini to add in the recent new SDF systems (vacuum, cds). DAQ+EDC restart required.

WP11194 Add Pulizzi power controls to h1cdssdf

Dave:

h1cdssdf was extended to monitor the outlet status of the pulizzi AC power control units. This is mainly to alert the control room if the PEM injection coil drivers accidentally are left powered up after maintenance. Several restarts of h1cdssdf on h1ecatmon0 was needed. No DAQ restart needed.

WP11192 Add 8 filtermodules to h1calinj to permit filter loading without error message

Jamie, TJ, Dave:

A new h1calinj model was installed. Two changes to the DAQ:

1 - six TINJ slow channels removed

--: slow channel H1:CAL-INJ_TINJ_ENABLE removed from DAQ 
--: slow channel H1:CAL-INJ_TINJ_ENDED removed from DAQ 
--: slow channel H1:CAL-INJ_TINJ_OUTCOME removed from DAQ 
--: slow channel H1:CAL-INJ_TINJ_PAUSE removed from DAQ 
--: slow channel H1:CAL-INJ_TINJ_START removed from DAQ 
--: slow channel H1:CAL-INJ_TINJ_STATE removed from DAQ 

2 - eight "dummy" filter modules added, needed to permit a clean load of the filter module file.

This was tested and it has indeed removed the error message we were getting.

DAQ restart required

WP11176 Pass all models' filtermodule files through 'foton -c'

Dave:

I completed passing all model's filter files though 'foton -c' and loading the new file. This will prevent bogus CFC flags if this were to be done during O4.

All new model installs are being foton'ized before the model is started.

New h1pemcs model

Please see separate alog for details. DAQ restart required.

DAQ Restarts

Jonathan, Dave:

two DAQ restarts: the first for all the above changes except h1pemcs; the second just for h1pemcs.

1st restart: gds0 and gds1 needed a second restart

2nd restart: gds0 was down for an extended period while its channel list was updated with the new h1pemcs model. gds1's chan list was modified before the 1-leg restart and gds1 did not in this case require a second restart.
