Weekly Maintenance on Nov. 11, 2019
[Oshino, Miyakawa, Kamiizumi, Tomura, Shimode, Yamamoto]

== What we did==

  1. Replaced a computer for k1fw1 as faster one.
    Downtime is from 9:41 to 10:37.

  2. Stopped the all circuits for k1pr3 and k1prm in order to change the DC power supply.

  3. Stopped k1test0 computer (on which k1grdconfig, and k1detdq is running) in order to remove unnecessary DAC cards.
    We entered EXV room from 9:50 to 10:50.
    ETMX was already in the safe state for Dr. Okutomi and Yamada-kun's work.
    So we never touch the ETMX guardian today.

I found the Dolphin was disabled on k1als0, k1imc0, and k1prm around 13:20.
Did anyone disable them?

k1imc0 and k1prm was fixed by rebooting computer around 14:00.
But k1als0 didn't come back. So I forced it to stop and boot again around 14:50.
