HPSS tape archive is now read-only

The High Performance Storage System (HPSS) tape archive that CISL manages became read-only for most users on Monday, January 20. The only exceptions are for a small number of curated collections such as the Research Data Archive. This is a preliminary step toward HPSS decommissioning in 2021.

While writing HPSS files is no longer possible, users can still read their existing HPSS files and perform most common metadata 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 has 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:

Training video and slides

Additional CISL Daily Bulletin 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: 
Tuesday, January 21, 2020 to Friday, January 24, 2020
