I requested all HEPI and ISI guardians for HAMs 2, 3, 4, 5 to "READY", then we restarted all the models on those computers.
I ssh'ed to the computers, h1seih23 and h1sei45, and ran "sudo /etc/startWorld.sh". Richard clicked some DACKILL reset buttons, and we're back. I requested the HEPIs and ISIs to their nominal states, and have started initial alignment.
The BLRMS that Jim has on the wall for HAM5 (alog 44661) look high, but I'm going to wait until he gets in to look into this - it's not stopping me so far.

Gabriele and Sheila had said that locking had been not very robust today, so I checked on the status of the ISIs. Restarting the ISI models zero'd all the gains on the sensor corrections on these ISIs (that was how Hugh and I set them in the safe.snap). The HAM sensor correction guardians didn't re-engage the sensor correction after the restarts. I found this by looking at some lights I added to the SEI_CONF overview. On the attached screenshot, there are a bunch of green indicator lights about a third of the way up from the bottom left corner, where it says "Sensor Correction Gain States". The only red light now is for the EX sensor correction, which is off because of the broken BRS. I guess I haven't advertised this before, but if there is a question about the seismic configuration, this screen is a good place to start. The sensor correction lights don't show everything, but should all be green if we expect everything to be nominal.
