Software upgrades - availability improvements
• NGF-HPSS integration is still in development and several years away from production
• Upgrading HPSS from version 5.1 to 6.2– eliminates our dependence on DCE– reduces need to take frequent planned outages– new HPSS account/password management process
• no more ssh to auth.nersc.gov• working to integrate with NIM• continue to allow regular ftp access with encrypted string
in .netrc file• password expiration
– non-HPSS specific password, but would expire– HPSS specific password, would not have to expire
• Email: jhick@lbl.gov or contact NERSC user services if HPSS password expiration would present significant challenges to you/your project.
