Overview

A planned To ensure the ASU Research Computing maintenance, as approved by the ASU Research Computing Governing Board will go into effect at the scheduled time listed below and impact the indicated systems.

Potentially Impacted Systems

• The Supercomputers and its subsystems.

• Project-based storage.

• Long-term storage (Canyon).

• Globus and its service-providing data transfer node.

• Colocated services.

Brief Description

Over three days, the supercomputers will be updated systems are safe and current, maintenance outages will be scheduled and carried out quarterly on the supercomputers and related infrastructure to maintain stability and improve performance and security. Jobs will not be allowed to run on the supercomputers during the maintenance period.

Expected impact

Jobs will not be allowed to run on the affected systems during the maintenance period. Pending jobs requesting wall times that overlap with the maintenance period will remain pending until after the maintenance has concluded.

Impact of maintenance if not carried out

Failure to carry out the required and critical updates will expose all computing, storage, and networking components to the inherent risks of active computing environments.

Additional details

The maintenance window was put into effect by scheduling a "reservation." This reservation may be viewed from the shell by issuing the command, scontrol show reservations.

Maintenance outages will be scheduled and carried out quarterly to ensure the ASU Research Computing systems are safe and current. The length and timing of these maintenance windows were carefully planned to minimize the impact of the University's ongoing research commitments. Estimated maintenance dates are subject to change. Communication is sent out via email before maintenance.

Maintenance

In the event of the need to install important security patches or perform other maintenance that cannot wait until a Scheduled Maintenance window, ASU Research Computing Staff will schedule critical maintenance as needed and inform users via email. ASU Research Computing Staff will try make extra effort to preserve currently running jobs if possible.
