Leonardo: anticipated maintenance on October 16th and temporary stop of production

Dear Users,
the scheduled maintenance of Leonardo is anticipated to Monday, October 16th, in the mid-afternoon, due to the necessary operations preparatory to the stop of the entire infrastructure. The stop is required by the test of the motor generator system and the power supply, scheduled for October 17th.
The login nodes and the access to the storage will be restored  on Wednesday, October 18th, while the booster partition will stay out of production until October 21st, with a possible further prolongation of a few days. This temporary stop of production is dictated by the need to finalize in an unperturbed environment the functioning tests of the Data Center/General Purpose partition for its forthcoming entrance in production.
We apologize for the inconvenience this may cause to your activities.
Best regards,
HPC User Support @ CINECA
