[Hallb-engineering] 1-hour hallbopi downtime this week

 Thanks for the heads-up, as of today April 16th @ 10:00AM it's working fine so I'll assume all went well with the security updates.
I do have a request that I spoke with Nick about implementing before all this virus crap hit the fan, so to speak.

It's about adding the beamline valve positions to the Beamline Overview Window. There are many times when it would be VERY helpful to me and several
others to properly interpret and diagnose vacuum conditions on the beamline. Without knowing the positions of the valves I am left to guess, look manually (if possible) or have someone pull up the accelerator engineering controls and read them out to me, not many know where they are hidden.
I'm aware it's controlled by the accelerator group but it's just one more read-only access 🙂

Not sure if it's something you can implement right now and it's totally understandable if you can't.
I've attached a .JPG showing the valve numbers, locations on the page and if you have any questions/problems please let me know and I'll help all I can.

Thanks Nathan,

Hello All,

To fix new critical security issues, JLab's IT group would like to take hallbopi down for patching for an hour this week.

The current plan is to do it the morning of April 16, this Thursday, 5-6AM, and I'll send out a reminder the night before, after the decision is final and also tested on a less important server.

Note, this does *not* affect our slow-controls alarms or notification systems, nor your ability to 2-factor login to the Hall B online systems.  It only affects read-only, web-browser access to Hall B slow-controls systems at this URL:


Impact should be minimal.  If you see a problem with this plan, let me know.
