Emergency Maintenance on NESE Tape Library

Completed
March 04, 2026 at 2:22 PM
Completed
March 04, 2026 at 2:22 PM
The Maintenance has completed successfully.
One hardware components in the library has been replaced.
The tape cartridges inventory has been reconciled. The Storage Archive service and Tape Library are up and running. Storage Archive shows NO missing or duplicated cartridges.
We will keep closely monitoring the service to confirm everything proceeds as normal.
Remaining items: One of the two accessors in the library robotic components was still showing small issues with calibration, so we have decided to leave it disabled for the time being, waiting for further troubleshooting from IBM. That will have only minimal impact on performance of the service.

We are still working with IBM to resolve the issue with the library inventory. We will further extend the emergency downtime for the tape library to Wednesday, March 4th, 9 am.

IBM is sending a hardware replacement part for the library tomorrow, and their support engineer will install that part tomorrow and re-launch the scan of the tapes in the library. According to support, we expect that replacing that component should resolve the issue.

If you have questions or concerns, of if you would like more details on the issue, please feel free to connect to NESE office hours session tomorrow starting at 1 pm, where we can provide any additional information we have, and the latest updates.

Thank you for your patience.

Office hours on Tuesday: 1:00pm -- 2:45pm

NESE Tape service is currently not able to store or recall files to and from tape due to vendor firmware issues in the tape library.
The issue is related to the library robotics and cartridge database, and we do NOT expect any data loss from this issue.
The issue is apparently due to an issue with the inventory database related to a recent firmware update. This database can be scrubbed and reconstructed by the library, which will scan the bar code labels on all the cartridges to rebuild the inventory.
Association of files in Globus to tapes is handled separately from the tape library and is not affected by the firmware update.
Similarly, USATLAS and CMS file to tape association was not affected by the firmware update. We are taking additional measures to preserve this information as we complete the work with the tape library inventory.
