Migrating data from HPSS during Cheyenne maintenance

July 9, 2020

The Cheyenne system is unavailable July 13-18 for scheduled maintenance, but other resources can still be used during the week to migrate data holdings from the HPSS tape archive. The Casper cluster, GLADE and Campaign Storage file systems, HPSS, and data-access nodes will all remain available except for Tuesday, July 14, from 7 a.m. until approximately 7 p.m.

HPSS will be decommissioned on October 1, 2021, and the tape archives have limited bandwidth. Users who wait too long to migrate their HPSS data holdings to other spaces such as Campaign Storage may run out of time to migrate all of their data and it will be lost when the system is shut down.

CISL documentation and this tutorial describe recommended processes for identifying and organizing HPSS holdings, for copying files that need to be preserved to another storage resource, and for deleting files that are no longer needed. Please contact CISL for advice on individual workflows and storage options.
