BS Camera stopped updating just like in alogs:
This takes the Camera Sevo guardian into a neverending loop (and takes ISC LOCK out of Nominal and H1 out of Observe). See attached screenshot.
So, I had to wake up Dave so he could restart the computer & process for the BS Camera. (Dave mentioned there is a new computer for this camera to be installed soon and it should help with this problem.)
As soon as Dave got the BS camera back, the CAMERA SERVO node got back to nominal, but I had accepted the SDF diffs for ASC which happened when this issue started, so I had to go back and ACCEPT the correct settings. Then we automatically went back to Observing.
OK, back to trying to go back to sleep again! LOL
Full procedure is:
Open BS (cam26) image viewer, verify it is a blue-screen (it was) and keep the viewer running
Verify we can ping h1cam26 (we could) and keep the ping running
ssh onto sw-lvea-aux from cdsmonitor using the command "network_automation shell sw-lvea-aux"
IOS commands: "enable", "configure terminal", "interface gigabitEthernet 0/35"
Power down h1cam26 with the "shutdown" IOS command, verify pings to h1cam26 stop (they did)
After about 10 seconds power the camera back up with the IOS command "no shutdown"
Wait for h1cam26 to start responding to pings (it did).
ssh onto h1digivideo2 as user root.
Delete the h1cam26 process (kill -9 <pid>), where pid given in file /tmp/H1-VID-CAM26_server.pid
Wait for monit to restart CAM26's process, verify image starts streaming on the viewer (it did).

Forgot once again to note timing for this wake-up. This wake-up was at 233amPDT (1033utc), and I was roughly done with this work in about 45min after phoning Dave for help.
