There is a blue box with the number 1 in it under the CRC column for H1ISIHAM3 on the O1 CDS detailed overview. I'm not certain what this means. Screenshot attached.

Relocking sequence:

Had to move both ETM and TMS for both arms to lock on green. Took a long time.
Stopped in CHECK_IR. IR not really found. Adjusted H1:ALS-C_COMM_VCO_CONTROLS_SETFREQUENCY and H1:ALS-C_DIFF_PLL_CTRL_OFFSET.
Modes look bad and flashes are low in power on LOCK_DRMI_1F
Starting initial alignment
Had to adjust ETMS to lock arms on green
Moved PR3 to slightly improve COMM beatnote
Done initial alignment
Had to adjust ETMY in Pitch to lock on green
Stopped at ENGAGE_ASC_PART3. Lowered diffracted power.
Had to rerequest READY_FOR_HANDOFF for OMC_LOCK node at DC_READOUT_TRANSITION. Got 'wrong node?' notification. Rerequested READY_FOR_HANDOFF. No change.
Put OMC_LOCK node to auto
It went back through the sequence and got to READY_FOR_HANDOFF
The ISC_LOCK guardian went on. While it was at INCREASE_POWER I put the OMC_LOCK node back to managed.
Got 'node OMC_LOCK: STOLEN (by: USER)' notifications on ISC_LOCK guardian.
Stopped at engage ISS second loop
Engaged ISS second loop by hand

Attempt to remanage OMC_LOCK node:
Put ISC_LOCK node to manual
Selected INIT for ISC_LOCK node
Got oh no it is unlocked voice, but it wasn't
Selected ENGAGE_ISS_SECOND_LOOP for ISC_LOCK node
Put ISC_LOCK node back to auto
Requested NLN for ISC_LOCK node

Made it to NLN!
