Hi Holly,

The GEM monitoring is working on the Rpi end. The IOC needs to be rebooted.

The log in information for the IOC needs to be updated in the troubleshooting guide. I’ll update it when I get the password.

Hi Holly,



We are working on a new SD card image now. Hopefully we can get that working by tomorrow.

Hi Marc,



Hall C will be open tomorrow morning after 7am for most of the day for a recovery day for the accelerator. Could you fix the GEM flow readback issue tomorrow? We will be in controlled I believe for the day.



Thanks,

Holly
