CDS Power-outage Recovery Update
CDS is almost recovered from last Thrusday's power outage. Yesterday Patrick and I started the IOCs for:
picket_fence, ex_mains, cs_mains, ncalx, h1_observatory_mode, range LED, cds_aux, ext_alert, HWS ETMY dummy
I had to modify the picket fence code to hard-code IFO=H1, the python cdscfg module was not working on cdsioc0.
We are keeping h1hwsey offline, so I restarted the h1hwsetmy_dummy_ioc service.
The EDC disconnection list is now down to just the HWS ETMX machine (84 channels), we are waiting for access to EX to reboot.
Jonathan replaced the failed 2TB disk in cdsfs0.
Jonathan recovered the DAQ for the SUS Triple test stand in the staging building.
I swapped the power supplies for env monitors between MY and EY, EY has been stable since.
I took the opportunity to move several IOCs from hand-running to systemd control on cdsioc0 configured by puppet. As mentioned, some needed hard-coding IFO=H1 due to cdscfg issues.
CDS Overview.
Note there is a bug in the H1 Range LED display, a negative range is showing as 9MPc.
GDS still needs to be fully recovered.
