Emmy in Göttingen, June maintenance
The core switches of the Emmy system were the root cause of several network related problems (luckily mostly not visible to the user side). This means we want to replace them. The core switch replacement requires a full downtime of HPC operation in Goettingen. We will combine this work with several maintenance and update tasks on the systems. We are facing a network problem with the connection of the login nodes. We have to fix this together with our network team tomorrow morning (June 16th) before production on the systems Emmy and Grete can resume.
The downtime will start on June 12th 8am. We expect the system to be available again in the course of Thursday June 15th.
