Additionally, there will be a separate scheduled maintenance at MGHPCC between June 5th and 6th.

As part of the work during the MGHPCC Outage, one of the Cooling Distribution Unit (CDU) in Pod 7c will be replaced. This will allow for future expansion into this space.

This work will run from Thursday Jun 5th until the evening of Friday June 6th. This means nodes whose names begin with holy7c02, 04, 06, 08, 10, 12 ​will not​ come back online after the outage and will remain down until this CDU update is complete.This impacts the following partitions. If you are using one of those partitions please use the public sapphire partition while your equipment is being serviced. These nodes will be returned to service once the CDU work is complete:
