On   at 08 UTC AA, the default Atos cluster will became unavailable for essential Slurm and security updates. In preparation of this session:

Any jobs still running on AA when the session starts will be cancelled.

During short transition phase it is possible that your batch jobs and interactive sessions to hpc-login are hosted on a different complexes. Consequently, some general Slurm commands (see HPC2020: Batch system) executed on hpc-login node will not be able to manage batch jobs running on another cluster. You can find more information on how to manage jobs between the different complexes in HPC2020: Multi-complex SLURM management.
