Update: Cluster Maintenance Will Continue onto Wednesday

Dear Users,

I am sorry to report that we encountered a significant problem while upgrading the firmware on one of the IB Gateway switches. The vendor was present during the upgrade and is aware of the problem. Because the IB Gateways provide connectivity for our Mobydisk Lustre filesystem and our Infiniband fabric, this issue directly impacts the HTC, MPI, and Frank clusters. While we believe this outage has limited impact on the H2P cluster, we wish to reassess the situation in the morning before attempting to bring part of the compute resources back online. We also aim to develop a contingency plan to bring HTC, MPI, and Frank back as soon as possible.

Please feel free to submit a ticket if you have questions or concerns:
