Cheyenne system returned to users after completion of OS upgrade

July 3, 2019

The Cheyenne system was returned to production late Tuesday evening following completion of the operating system update and system verification. As noted in previous communications, users are advised to to rebuild their executables and thoroughly test all scripts. Many system libraries changed in the new version of the OS, which is SUSE Linux Enterprise Server (SLES) Service Pack 4. Executables built before the upgrade are likely to fail.

Other significant changes were made to the module environment during the upgrade, and users can now manage their Campaign Storage data holdings with POSIX commands. See these new Daily Bulletin items for details:

Please report any suspected issues with the new user environment as soon as possible to cislhelp@ucar.edu. Thank you all for your patience and cooperation throughout this extended outage.
