Scheduled exceptions and downtimes
To sustain future growth, the power load in the HPCC server room needs to be optimized. For this we have scheduled an HPCC (Biocluster) shutdown in four weeks from now which will start at noon on June 16th and last until noon June 17th. This will require a shutdown of ALL services: Slurm (queuing system), hosted websites, virtual environments/machines, storage access, backup systems and network services. We ask that you please make sure that you do not have any jobs running in the queue, and that you completely logout of the cluster (pigeon, owl, penguin, pelican, globus) before the shutdown.
SOP for scheduled shutdowns
Standard operating procedures for scheduled shutdowns are here.

10:02 AM, 13-Apr-17: UPS failure
Our UPS unit went down some time last night causing a power failure on all systems. Jordan is bypassing the UPS to bring things back up in the next few hours. Nationwide Power will come in asap to repair the UPS. Note, this failure has not resulted in any overheating problems since the AC units are running on a different power cricuit.
11:22 AM, 13-Apr-17: Cluster back up running
Situation is resolved for now and things are working. We are currently discussing the situation with our electricians to avoid future instances.
