No scheduled downtime: Cheyenne, Casper, Campaign Storage, GLADE, HPSS

Video and slides from the December 4 tutorial “Migrating Files from HPSS” are now available here in the CISL training library. The 40-minute presentation by Brian Vanderwende of the CISL Consulting Services Group provides guidance and best practices for moving files from HPSS to alternative storage facilities.

Topics covered include:

  • Obtaining information about HPSS data holdings

  • Moving files to external storage platforms using Globus and Linux utilities

  • Moving files to Campaign Storage via the data-access nodes

HPSS will become read-only on January 20, 2020, and be decommissioned in 2021. Users are advised to begin evacuating their holdings from HPSS immediately.

See related documentation: Migrating Files from HPSS.

Anyone who uses NCAR/CISL high-performance computing, data analysis, and storage systems is welcome and encouraged to let us know how we’re doing, suggest improvements, and provide other feedback.

Our recently introduced NCAR Research Computing support portal even includes a dedicated “Feedback” form to make it easy for you to share your thoughts and suggestions. In addition, when we resolve an issue or fulfill a request that you submit through the portal, you’ll get a follow-up email asking you to rate our service on a scale from “Very poor” (we hope not!) to “Very good” (our goal).

Be sure to take advantage of these opportunities to let us know how well we’re meeting your needs.

Users are reminded that the High Performance Storage System (HPSS) tape archive will become read-only on January 20, 2020, with exceptions only for curated collections such as the Research Data Archive. This follows the announcement in October 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 as soon as possible.

Recently published documentation – Migrating files from HPSS – describes 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. 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, accessing data movers, and storage options.
