Cheyenne maintenance outage scheduled for Tuesday, February 6

February 2, 2018

Cheyenne will be unavailable on Tuesday, February 6, starting at approximately 7 a.m. MST to allow CISL staff to update system software components. The outage 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.

A system reservation will prevent batch jobs from executing after 7 a.m. All batch queues will be suspended and Cheyenne’s 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.

Jobs and interactive sessions that are running on the Geyser and Caldera clusters when the update period begins will not be interrupted but users will not be able to log in to or submit new jobs to those systems until Cheyenne is returned to service. Users who need access to the Geyser or Caldera systems on Tuesday are advised to initiate an interactive session before 7 a.m. on Tuesday.

CISL will inform users through the Notifier service when Cheyenne is restored. We apologize to all users for the inconvenience this will cause and thank you for your patience.
