On Monday, August 25, the Eagle filesystem will be temporarily taken offline for a scheduled software upgrade and hardware maintenance. During this time, Polaris, Sophia, Crux, and EDTB will be unavailable, along with projects stored on /eagle (/lus/eagle/projects) and /grand (/lus/grand/projects). Additionally, the Globus endpoints alcf#dtn_eagle and alcf#dtn_grand will be inaccessible. The storage upgrade should be complete by Wednesday, August 27, at which point Sophia, Crux, and EDTB will be returned to service. 

Polaris will undergo an additional HPCM upgrade and is scheduled to be returned to service on Friday, August 29. Users are strongly encouraged to recompile code to avoid issues once the upgrade has been completed.
