Summary:
The SDCC Facility and Science DMZ will undergo scheduled maintenance from Monday, December 18th, starting at 5 PM, through Tuesday, December 19th, until 9 PM EST.



Effective Time(s):
12/18/2023 5:00 pm - 12/19/2023 9:00 pm

Group Responsible:
Network

Affected Area(s):
All SDCC services

Expected User Impact:
No access to SDCC services during downtime

Maintenance Type:
Planned Maintenance/Downtime



Description:
This extended downtime is necessary for two key activities: upgrading user home directories beginning on Monday (for all programs but the NSLS) and a network maintenance scheduled for Tuesday (affecting all customers). This maintenance marks the final phase of the multi-year migration of SDCC services to a new data center.

Impact on Services:
- Storage and Data Transfer Services: Access will be suspended starting Monday, December 18th, at 5 PM EST to allow for a clone of the user&amp;rsquo;s home directories. Special Note for NSLS Program Users: The NFS home directory work scheduled from Monday to Tuesday does not impact the NSLS program. NSLS program users should expect regular operation during this period (until the network maintenance begins on Tuesday).
- Computing Resources: Access to computing resources (interactive and batch), storage services (disk and tape), and collaborative tools (BNLBox, RCF email, MatterMost, web services) will be unavailable throughout the respective maintenance periods. - Batch Job Scheduling: Scheduling of new HTCondor and Slurm batch jobs will cease on Friday, December 15th, at 11 PM EST. Any remaining HTCondor jobs will be terminated on Monday, December 18th, at 3 PM.
- Interactive Sessions: Open sessions through the facility SSH gateways will be terminated at 5 PM on December 18th to facilitate the cloning/copying of user home directories.
- Email Services: The @bnl.gov email services may experience interruptions. Alternatively, users are encouraged to use the sdcc-staff-l AT lists.bnl.gov mailing list to contact SDCC staff.
- NX Service and SSH Gateway: The NX service and SSH Gateway will be unavailable. Existing cssh sessions initiated before the outage will continue to function.

Restoration of Services:
Complete restoration of services is anticipated by 9 PM EST on December 19th. The SDCC will notify the community through its regular mailing lists.
We apologize for the inconvenience this may cause and thank you for your understanding and cooperation as we complete this essential upgrade to our infrastructure.
