Reminder: Extended Cheyenne downtime scheduled for February 25-29

February 10, 2020

The Cheyenne cluster will be unavailable to users in late February to allow CISL staff and HPE engineers to perform critical infrastructure maintenance, repairs, and system software updates. The maintenance period will begin early Tuesday morning, February 25, and the system is expected to be returned to service no later than Saturday evening, February 29. This will be Cheyenne’s last scheduled outage until the third quarter of this year.

The Casper cluster, GLADE and Campaign Storage file systems, data-access nodes, and HPSS will remain available throughout the week except for approximately four hours beginning at 8 p.m. MST on February 25 while a key network infrastructure component is rebooted. Watch for more details and updates in the CISL Daily Bulletin.
