Cheyenne compute nodes are down following cooling system failure

October 21, 2019

Cheyenne’s compute nodes remain down this morning following a cooling system failure on Sunday. CISL continues to work with HPE to determine the root cause of the failure and the steps necessary to safely restore the system as soon as possible. The situation is at the highest severity level with HPE support and engineering. No ETA for returning Cheyenne to full service was available as of 9 a.m. today.

Cheyenne’s login nodes, the Casper cluster, the GLADE file system, Campaign Storage, HPSS, and the data-access nodes all remain available to users. More information will be provided via Notifier as it becomes available.
