Accessing HPSS
Once you have successfully set up your account and password, you can access HPSS using the HSI and HTAR utilities, NERSC's PFTP utility, clients that use the FTP protocol. and grid-enabled clients.
HPSS cannot be accessed via SSH.
Access from NERSC platforms
HSI, HTAR, and PFTP are available on NERSC platforms. The default HPSS system is archive and need not be specified on the command line. The older regent HPSS system should be specified as "hpss" when using the HSI utility at NERSC. Specifying the full DNS names archive.nersc.gov or hpss.nersc.gov will result in network traffic using slower external networks.HPSS can be accessed interactively and used in batch scripts.
The first time you log into HPSS with HSI, you are prompted for your "DCE Principal" (NERSC username) and password and an .hsipw file is created in your HOME directory. The next time you access HPSS, HSI will use the information contained in this file to authenticate you to the system. You will not be prompted for a username/password pair. Occassionally this .hsipw may become corrupted. If you have trouble connecting to HPSS, try removing this file and reauthenticating.
Access from outside NERSC
The NERSC production HPSS system is known as "archive.nersc.gov". "hpss.nersc.gov" is the "regent" system that is used for system backups, although it does contain some older user data.
archive.nersc.gov can be reached using the hsi and htar utilities and ftp clients. The HSI utility is available for download and use by NERSC users. FTP clients have to use a special process for encrypting username/password pairs.
