Reminder: HPSS tape archive becomes read-only on Monday, January 20

Users are reminded that the High Performance Storage System (HPSS) tape archive will become read-only on Monday, January 20. The only exceptions will be for curated collections such as the Research Data Archive. This follows the October 2019 announcement that HPSS will reach its end of life and be decommissioned in 2021.

While writing HPSS files will not be possible as of January 20, users will still be able to perform most common meta-data operations on their HPSS holdings, including deleting, renaming, and moving files. Those who have not already done so should begin deleting files that are no longer needed and moving other data to alternative storage systems.

CISL recently published documentation and training for users on recommended processes for identifying and organizing HPSS holdings; copying files that need to be preserved to another storage resource; and deleting files that are no longer needed. Follow these links:

Additional announcements will follow as new tools, training, and expanded documentation become available to support the data migration. In the meantime, please contact CISL for advice on individual workflows and storage options.

Announcement Timing: 
Wednesday, January 15, 2020 to Thursday, January 16, 2020
