Lots of issues keeping GREEN_ARMS locked (maybe from microseism) and finding IR (keeps missing DIFF), we're unable to survive past CARM_TO_TR. The common mode servo board output signals don't look abnormal, there was some glitching but trending back it usually does this. I tried holding at START_TR_CARM and PREP_TR_CARM and we can survive, I looked at a bunch of the signals and they all seemed normal, MICH, ADS, IMC/LCS REFL_SERVO. When I tried to move on I got the NO IR in arms and we lost lock. Other times in the same state we lost lock at various stages of the CARM gain reduction.
Both the arms have been pretty unstable the whole shift (Y more so), but the wfs has managed to keep it locked for a decent amount of the time, it got worse towards the end. While the microseism is high we've been able to lock with it at the same levels before so it's probably not the sole issue but it certainly isn't helping.
All of the test mass BSC ST2 sensor correction guardians were complaining of being in the wrong state. The gains were all zero for these, so all of the test masses were moving more than intended at 1/2hz. Init-ing these guardians recovered the gains, then I init'd the SEI_ENV guardian to get everything back to managed. This allowed Austin to get past DRMI and finally to NLN. I should have glanced at this after hearing about the front-end crashes on Friday, all of the ST2 SC guardians had yellow notifications, so it was easy to spot. When we restart an ISI front-end we should probably cycle SEI_ENV through maintenance then back to CALM to make sure everything is in the right state.
