STATE of H1: Observing at 147Mpc
INCOMING OPERATOR: Ryan C
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 13mph Gusts, 8mph 5min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.24 μm/s
SHIFT SUMMARY:

1:09 UTC got to PREP_DC_READOUT_TRANSITION
Noticed about about 15 minutes later that we were in this state for much longer than usual.

OMC should be trying to get to READY_W_NO_WHITENING but it is saying :

[SET_WHITENING.run] USERMSG 0: DCPD gains not equal after whitening switch -- yikes!
I tried poking it around to a few different states but it seemed to get stuck at the same state each time.

Ryan told me he had seen this before, I found Ryan's Alog and read through it.  I'm not sure if I have the right channels or not.
H1:OMC-DCPD_{A,B}0_GAIN Is what I scoped back to June 6th and saw that they were indeed changed that day.
Seeing as I couldnt find the full length of those channels on the OMC screen I did a caget and caput and was greeted with a failure to to write error.

CA.Client.Exception...............................................
    Warning: "Channel write request failed"
    Context: "op=1, channel=H1:OMC-DCPD_A0_GAIN, type=DBR_STRING, count=1, ctx="H1:OMC-DCPD_A0_GAIN""

I'm not sure why that was but  Jenne D told me to try: 
cdsutils write CHANNEL_NAME SetPoint
cdsutils write  H1:OMC-DCPD_A0_GAIN 1  worked out well for both A and B Channels and got the OMC going again.

2:24 UTC Reached OMC_Whitening, Waiting for Violins to go Down.

3:17 UTC Nominal_LOW_NOISE reached

made it to NLN but not in Observing because SQZ_MAN got stuck in FC_WAIT_FDS:
I requested SCAN_SQZANG, to see if that would allow it to cycle through the stages but it got stuck there again.

Naoki jumped on the chance to help the SQZ Manager make it to FDS
I saved some SUS Spot Gain SDFs And an LSC SDF.
4:02 UTC Obsering was reached!

H1 has been Locked and OBSERVING for 4 and a Half hours.
