System downtimes scheduled for Tuesday, October 2

October 2, 2018

The Cheyenne, Geyser, and Caldera clusters and the GLADE file system will be unavailable on Tuesday, October 2, starting at approximately 7 a.m. MDT to allow CISL staff to perform system maintenance on important hardware and software components. The downtime is expected to last until approximately 6 p.m. but every effort will be made to return the system to service as soon as possible. The planned updates include the previously announced changes to GLADE file spaces and repairs to damaged InfiniBand switches.

A system reservation will prevent batch jobs from executing after 7 a.m. All batch queues will be suspended and the clusters’ login nodes will be unavailable throughout the update period. All batch jobs and interactive processes that are still executing when the outage begins will be killed.

CISL will inform users through the Notifier service when all of the systems are restored.
